Air Conditioner Noise & Leak?

[Dawn Eshelman]

I was driving home on Monday, when I noticed my car making noise when I made turns. Upon closer inspection, I discovered it was when I made left turns. It sounds like a rainstick...or gravel and water sliding from the driver's side of the car to the passenger's side. THEN I noticed what appears to be water running out from under the dash on the passenger floorboard. There was enough water to completely soak my floormat!:frown:

Any one experienced this problem yet? My car just hit 1 year, and 15,000 miles. Is it an air conditioner leak?

I operate my air conditioner with outside air, because when I operate it with recirculated air, it really stinks!

[gonzo452001]

take it to the dealer

There is either a leak, or clog. The condensation is not draining and just puddling in system.

[tekmoe]

having this same exact problem! just noticed it today! i took the glovebox compartment out and pulled up the carpet on the passenger side. i found where the leak is coming from. it appears to be condensation from the A/C. it does indeed look like it is not draining properly.

gosh darnit.

[brickhardmeat]

there's maggots everywhere!!!!!:barf:

[Artymuse]

I have this same problem in my '09 Yaris (minus the maggots brickhardmeat mentioned). Gonna take it in this afternoon to get it looked at since its still under warranty. I've only got about 3,700 miles on it and just bought it in January '09.

Took me a few days to notice the leak after the noise had been getting progressively worse. The smell started to build up too, but after i pulled out my floor mat the smell dispersed. I keep a little foil made trough under there now that catches all the water til i can get it fixed.

[CTScott]

There are a few threads on this issue. The condensate drain hose is plugged, causing the backup. This is very common in the spring when the trees drop all of their stuff.

You can clear it yourself using something like a tiewrap (flexible plastic item). Gently insert it into the condensate tube from under the car, and the water should come gushing out.

I do have the same issue with my 07 Yaris I took for the car to Northridge Toyota ;The third time for the issue describe above on June 5th 2009 They want to charge me because my car is over 52,000, my warranty is up and they told me it would be charge to diagnostic the same issue on the car has been repaired under the warranty twice.I declined,and
I escalated to Toyota Motors They get in the same position as the dealers saying the following : The dealership determined that the failure was not a factory defect rather it is a customer related problem. Mr XX is leaving his car in a unprotected area. The drain hoses for the a/c on his Yaris are being plugged by foriegn debris causing the water to back up in the evaporator and is causing the leak into his vehicle. He was told on both occassions that this is not a warrantable issue outside influences are not covered by Toyota. On his two previous appointments the debris was cleaned out of his vehicle as a Goodwill gesture from Northridge Toyota and the Factory. He has complained to Toyota Motor Sales and Toyota has turned him down for any Warranty assistance. Mr XX Yaris is now out of the Factory Warranty. Knowing that I went to different Dealership : Thanks to service Advisor and his mechanic explained me the issue why it get debris inside the a/c box I understood clearly is a manufacturer issue because if you put anything in your glove compartment when you have the A/C button in circulation mode the A/C Box sucks air inside of the box causing with the time the drain plug be clogged and the fluid will leak inside the passenger side under the carpet.In order the A/C drain plug don't get clogged you can't put anything inside the glove compartment.
This is Lemon issue affecting most of the Toyota Yaris Hatchback 07-up
If you guys get the same issue as my self hit me up for legal referal against Toyota Motors.

I have the same problem, except now my fan does not work at all. A friend blew out the hose, it was clogged with dirt. He called Toyota and they said they have never had that problem before!!! My vehicle is no longer under warranty, just the power train warranty. How expensive are we talking?

[UpLateAgain]

I have the same problem with my Yaris..... exact same symptoms.... left turn produces water in passenger compartment with the noise of water flowing through the heater/ AC fan. It happens either when I run the air conditioner or after/ during a rainfall. The dealer told me it was a plugged drain tube and jacked up the car to show me where to blow it out. We did. It didn't help. My carpeting is starting to smell moldy and will probably have to be replaced. The car is a 2008, with 40k miles on it.... just enough to be off warranty.

So far the dealer doesn't really have an answer for me, and has told me it is essentially a design flaw. They are contacting Toyota and asking for advice, but i don't hold out a lot of hope.

I have owned a number of Toyotas, and always been tickled pink with them. This is turning into a major disappointment.

[CTScott]

Don't ever blow out the tube (unless you do so from inside of the airbox), as you just push the material back up into the airbox, where it will clog the tube again. If you ran without a cabin filter for a while, there could be a lot of stuff in the airbox, so clearing the tube once will not be a permanent solution anyway.

Install a cabin filter, if you don't already have one. To really clean the system out, the bottom of the airbox needs to come off. That requires some significant disassembly of the dash, but it would be worth it if it has the stink or continues to back-up.

[ottomobileY]

Hey Tenaz I Just started to experience this problem with my Yaris and it stinks literally Dude my car smells like mold. I was wondering if anyone on this forum has been able to fix this problem, looks like nobody has so far. Well if any one has, let me know what is it that you did to fix it. Tenaz let me know if you are gonna go ahead and take legal action. If there is anything you need like a letter or pics let me know.

And where might this elusive drain tube be? I'd like to see if I can roto-rooter it myself with a pipe cleaner or some cable from an old bike brake.

[CTScott]

The easiest place to get at it is from inside of the car, on the passenger side foot well. If you look under the top left corner of the carpet there (right by the center console) you'll see the rubber hose going into the floor. You can easily pull out the grommet and the end of the hose is right there. Just have a pan or bucket ready, so you don't make a mess of the carpet.

[Rick Flynn]

My 07 Yaris has been leaking for a few weeks on the passenger side--just like the rest of you.

It has 60K miles so no warranty.

A mechanic checked the drainage hose for AC condensation and it was fine, yet it still leaks, especially when I take a left turn.

Not every day, not when hot, not when cold, and not in a direct response to using the AC (yet it is summer so I often use it).

Not sure what to check next.

Any guesses?

Thanks,

Rick

Double check the condensate drain. If you're getting the left turn sloshing, then the drain is plugged and your air box is full of water.

[Rick Flynn]

Ok. That's sounds easy enough, except that I don't know what that is nor do I know where that is.

Not too handy!

Thanks!

Check out this post for a pics of where the tube is located. It is accessible from inside on the passenger foot well. If you try to clear it just have a pan or bucket under it to catch the nasty water that comes out.

That was very thoughtful and, yes, that tube was actually okay, but it's tank above that needs cleaning, and that's tricky. By the way, the dealer admits it's a design problem, but they're not taking responsibility for it. Odd, that Toyota would let something like this pass without fixing it.

Thank you!

I put my notes as I did on this forum.
U.S Yaris 2006 -? has this A/C issue believe me is a design problem.
At least I found 3 people with the same issue I had.
For Toyota is easy to say I take a complaint and we look into and done nothing.

The tank did not drain when my mechanic checked the hose and the local Toyota dealer (Fremont CA) wanted 80-150 to diagnose the problem which I'd already had diagnosed. Wondering what to do, I finally had a moment of inspiration--not bad for a clutz like me--and I thought, "Why not remove the drain hose and stick a clothes hanger up the hole"? Well, it worked. Water poured out of the tank, and the leak has not returned for two months.

^ that has been stated several times already in this thread..

[tenaz]

To avoid water leak in the passenger side you need to do the following:

1st thing you need to do is cleaning the A/C drain located in the passenger side botton left side.
2nd you can't put anything on the glove compartment.
After the A/C drain is cleaned.
Then You can stil use the a/c in circulation mode.How ever you glove compartment can't be use.

Hope this help for now

As long as you have a cabin filter installed, putting things in the glove box is a non issue.

Yeah You may be right.
But I was Told by a Senior Toyota Technician it will decrease the power from your A/C. If not why Toyota has not installed it .. ? :iono:
And avoid this issue all the Yaris's owners are reporting with the A/C system.
I do have 3 other cars besides the Yaris I don't have the same problem as the Yaris's has...

It will decrease the overall flow, but considering that if you take in outside air, the filter is the only thing that will prevent airborne stuff from entering the airbox and plugging up the drain, I couldn't imagine not running one.

I think the lack of them on USDM cars is either an oversight or a cost thing.

All this issues take to the other thread found here:

Toyota should take care of this issue as major recall to have proper fix the a/c design on all Yaris 07-08.
Until now I was not aware of this Technical Service Bulletin about the HVAC Odor Affecting all 07-08.(0103-09).
Thanks to the fellow member he post it for us.
I do own another 3 vehicles and in the past I owned several others Toyotas among them and never I got an issue like I do have in the Yaris

The ac unit on my 2008 Yaris, still less than two years old but over 36,000 so no warranty, is dripping water incessantly onto the passengers side floor.
Exactly as with everyone else on this posting. Left hand turns make the water run out of the pan and all over the passenger's feet.

Bullshit. Way to go toyota. We have another storm brewing for you.

did any of you buy the extended warranty?

depending if you did and which policy you got jus need to pay the deductable

[royalbitchx]

I've got this same leak on the right side passenger floor coming from right below the glove box and now my carpet is moldy (fantastic). I have a 2007 yaris sedan and I think I have the extended warranty so I might be saved but I buy toyotas because they're reliable this kind of bullshit shouldn't be happening. Just like the gas pedal/brake recall way to go for toyotas "reliability":bs:.

You don't need to have extended warranty on this.
Why you have to pay for something the Manufacturer didn't do right..?
Again this is design issue is found in the Yaris 07 hatchback.

This has been an issue in my Yaris since the first summer I used the A/C (note: also the first summer I had the car.)

I have found the best tool from under the car is a heave gauge guitar wire. Thanks for the tip on the in-cabin option - I think that will be far easier than having to jack the car up every time I have to do this. My dealer basically said there is no fix for it, and the best thing to do is to continue emptying it.

Don't let it go too long, though! I just found out today that I burned out my blower motor, and will now need to replace it.

I am competent enough to change a tire, and check oil, etc. I am pretty good at directions. Would this be a repair I might do myself, or would it need a lot of tools I don't have? I just don't have the money to pay to have it done, and no cabin air is a real bummer.

Replacing the blower is not bad, as it is at the bottom of the stack, behind the passenger glove box. Are you sure that the blower is actually bad? Will it not spin at all, or is it making noise?

[MiniSipperton]

I had this exact thing happen on my 08 hatchback. I did try unclogging the hose which was only a temporary fix. I finally took it to the dealership on Saturday as it was due for a warranty maintainence. When I dropped it off the service guy scratched his head and seemed mystified. However, when the service manager called later that afternoon she stated that this was a known problem and would be covered under the warranty. She also stated that they had to order a new part and it would be in Tuesday and possibly fixed by Wednesday. The new part had something to do with the cowel. Happily enough, she also said they would be detailing the car to get the stink out of the rugs. I'm hoping when we go to pick it up today that all she said holds true.

I'll get back to the forum tonight to report the new part and any other details that might be of interest.

[JamieTC171]

My '07 hatchback has been leaking for awhile. Today I finally took out the drainage tube and stuck a coat-hanger up into it to drain it out. A whole lot of nasty water came out but when I was driving it afterwards with the a/c on full, no air is blowing out. Sometimes the air will come out just a tiny little bit(it's cold air) but then it quits coming out again. How do I go about fixing this? Is this something I can do/fix myself or should I go to the mechanic? My car is not under warranty and I'm a broke college student so any fix that I can do myself would be great.

[crazedpenguinattack]

I have had this exact same problem twice now. I've had my Yaris for 3 years and I just hit the 31000 marker. The first time it happened was a year ago and Toyota fixed it under the warranty because there was a crack somewhere.
It started happening again so I took it in right away thinking it would be the same thing. There's no crack this time, they said it's leaking becuase the hose is clogged by leaves. They say it's not covered by warranty because the leaves are an "outside source and I parked in an unprotected area". Toyota wants me to pay $700 bucks to clean my soaked carpet and to unclog the hose!! No thank you I can do it myself!
Now I see that it is a commom fault with this model car. I have always heard such great things about Toyota, which is why I was sure to purchase my first new car from them.
I am so angry that they are fully aware that this is such a commom problem and yet refuse to take measures to fix and prevent it. I will never buy a Toyota again.

Yup Toyota tried that with me.
Toyota is a company that is concerns to make $$$$ only after you own the car they don't care about you as a Customer.
Thats why they have a bunch of Law suits In process.
They used the same tactic with the Camry and the Prius Now After the Federal Gov proof them those cars have some issues....They just now accepting some type of responsability.....
I hope by my court date I have the report from http://www-odi.nhtsa.dot.gov/defects/
I want to know by then What is going to be Toyota's Answer.

Pm: Everyone having the same issues with the A/C should report to the link above.
So Toyota can take care of our Yaris's a/c issues.

[yarisarisheris]

So glad to find this forum and more precisely this thread. My wife's 08 Yaris was experiencing much the same thing. I suspected a condensation buildup on the exterior of the A/C duct work, etc as we couldn't locate a specific leak location, but after reading through your posts, I turned my focus on the drain tube.

Oddly when I pulled the grommet end if from the firewall, the whole tube (~6-7 inches) rested neatly in my hand. The tube was not plugged after all, but instead the tube must have slipped off the plastic drain port at the base of the pan. I could find no hose clamp or much in the way to offer resistance to prevent the rubber tube from sliding off should someone stretch out their legs a little "too far" and dislodging it.

I checked to make sure everything associated with the drain was clean before reattaching the tube. Now the waiting game . . .

Cheers!

[Ivy23]

Happy to have found this forum, but so aggravated with my '08 Yaris sedan. I've always had bad odor with the a/c in re-circ mode. Blamed it on my husband's smoking, never realized it was a design flaw. Then started having the mildew/mold odor, but didn't think much of it. Now I'm experiencing the running water sound when making left turns. Noticed it 2 days ago, and it's getting progressively worse. Thanks to CTScott, I accessed the drain hose. Unfortunately, nothing comes out, even after I fed a large plastic tie strap up the hose. I also removed the glove box and found no debris blocking the intake. Of course, this car is not equipped with an air filter. Oh yeah, at just over 90K miles, no warranty coverage, not that Toyota would cover it anyway. Now what? I'm totally bummed about this whole thing and am scared that continuing to run the a/c will cause damage. $ is a major concern and would like to DIY as much as I possibly can. Any suggestions are greatly appreciated.

[Ivy23]

Solution for clogged A/C drain - I read through all these posts and tried to unclog the condensate hose both from under the vehicle and by pulling up the carpet on the passenger side and accessing the hose from inside the vehicle. I was unable to unclog the drain. This morning we were successful. We used a wet/dry shop vac. First a short blast of air into the hose to dislodge the clog, then suction to drain everything out. It appears to have worked. Now we are cleaning the carpets and installing an in-cabin air filter. Fingers crossed that this doesn't happen again.

Just had the same wet rug condition in my 2008 Yaris sedan. I first want to thank the previous posters for the great suggestions and pics. I used a thin 14" cable tie to dislodge the the clog followed by the shop vac to suck out any remaining debris. I used a cup to catch the backed up water (which I promptly knocked over). I've only had this leak for a few days and the smell was minor. I used the wet vac to dry the carpets and hopefully this will last for a while.

Thanks again.

I am having same issue. I cleaned drain line and 3 weeks later it started leaking again. This time I pulled drain line off and it is not clogged. It looks like water in the plastic container that the drain line hooks to. Can I try to use a piece of wire and push it in the hole where drain line connects to. With out a mirror I cant see in that hole but I gently tried a piece of wire and I didn't seem to slide in at all. I have a 07 with 98,000 miles and no cabin filter from factory. I did manage to get enough water to fill a gallon milk container with just over an inch of water after cleaning line.
So, I am wondering if where the drain line hooks to plastic container if that should be a big opening or not as my wire didn't want to go without forcing it

[slick1]

1) Lift up the carpets on the front passenger side of the car.
2) Disconnect rubber hose (top right hand corner) from the airbox.
3) Unplug rubber plug in the bottom of the car (underneath the carpet) to allow water to drain
4) Stick a hanger or stiff piece of wire into the hole in the airbox (and shake it all about)

Only took a few minutes to do.

I have pictures if someone would like to see what the hose looks like (this site needs a file area?).

Much simpler than accessing it from underneath the car.

Much cheaper than the dealers who quoted about $300 to do it (said they needed to rip everything out).

The dealers also claimed they'd never seen this problem before.

The smell seems to be mold or something from the airbox/carpet... and starts to disappear after the car has dried out.

I'm really disappointed by the Toyota response. This is obviously a common problem which they should be able to diagnose on the spot.

The solution is probably to fit a larger hose and/or to provide easy access to clean the airbox.

This is a manufacturing issue... and Toyota should address it.

Thanks very much to those who posted information which helped to diagnose this problem.

[Jassa123]

Hello all, i am very excited to say i just fixed the water leaking from under the dashboard on the passenger side. I called up toyota 2 days ago with my problem and was told it would be an all day job and they would have to remove my dashboard (would cost around $400) They said my air con was blocked and was causing all the water to leak into my heater box and then run onto the floor. Well i thought that sounded like BS and so decided to google the problem and found many people with the same issue. The solution is simple.

Under the dash on the passenger side, pull back the flap of carpet a little bit and on the right hand side, down low, there is a little black soft tube that is leading to the outside of the car. Just pull on it and it will easily pop out. Dont worry it will pop back in afterwards. Then get a stick or something flexible and stick it up the tube being gentle. Water will run out when you have unblocked it. then plug it back in and the problem is fixed. No more water on your floor. I am a 28 year old girl with no expereince in cars and i fixed it so dont go to Toyota for this problem and save yourself $400. Good luck everyone. Hope this helps all with the same annoying problem. :)

[Jassa123]

I agree Toyota are absolute A holes... they quoted me $400 to fix and i fixed it myself in 2 minutes the way you said... very very disappointed and angry with them..
Also it shouldnt happen in a new car in the first place

Hello all, i am very excited to say i just fixed the water leaking from under the dashboard on the passenger side. I called up toyota 2 days ago with my problem and was told it would be an all day job and they would have to remove my dashboard (would cost around $400) They said my air con was blocked and was causing all the water to leak into my heater box and then run onto the floor. Well i thought that sounded like BS and so decided to google the problem and found many people with the same issue. The solution is simple.

Under the dash on the passenger side, pull back the flap of carpet a little bit and on the right hand side, down low, there is a little black soft tube that is leading to the outside of the car. Just pull on it and it will easily pop out. Dont worry it will pop back in afterwards. Then get a stick or something flexible and stick it up the tube being gentle. Water will run out when you have unblocked it. then plug it back in and the problem is fixed. No more water on your floor. I am a 28 year old girl with no expereince in cars and i fixed it so dont go to Toyota for this problem and save yourself $400. Good luck everyone. Hope this helps all with the same annoying problem. :)

Nice job. I have this problem every fall as my driveway in under trees and I get the falling leaves on my car. Had to clean it 3 times last year. I rarely go to a shop for repairs.

My wife asked me to look at her Yaris which was making a sloshing sound when it turned and there was some condensation seeping onto the passenger side floor mat. I took the bottom cover off and saw the A/C was full of water and was not draining. It was also creating condensation, which in turn, leaked into the passenger compartment. The condensation was easy to wipe up and I pulled the mat out to allow it to dry. I took a basting bulb and sucked out the water from the clogged drainage under the car. Do not blow into the drainage hole because you will only cause more problems. The baster bulb will cost you about $2.75 at your local grocers and you will use it again when you baste that turkey at Thanksgiving. It took about 4-6 squeezes to really get the water to start draining. It beats leaving your car at the dealership too.
Cheers!

I have the same problem with my 2008 Yaris. Last summer was the first time I noticed the condensatation dripping onto the passenger side floorboard and the "water noise" whenever I made a turn. I took it to my dealer and they said a dirt dauber nest had clogged the drain hose. Fine, no problem for the rest of the season. Now, the first time I used my A/C this spring, the exact same leak returned. I searched the web and discovered that others are having the same trouble with their Yaris. Someone posted the pics of the drain hose under the floor matt and how to ream it out. I did that just now and got the excess water to drain out of the box. I used a ground wire from some Romex I had in my garage to poke up into the hose (apprx. 9 inches into hose and I rounded the tip by bending it back to keep from puncturing the rubber). Turned on the car and the A/C until condensation started dripping freely.....fixed!! I am keeping the carpet pulled up until the pad dries completely because it is starting to smell rank. I took out the door to my glove box, which was stuffed with manuals and what-not as well as a polishing mitt, which, I suspect, was being sucked into the air flow whenever the A/C was circulating. I have emptied the box and will keep my manuals in the upper compartment on the dash from now on to facilitate air flow. I hope this keeps thing operating smoothly. Thanks to the Yaris forum for providing valuable knowledge and tips.

For all you guys having this problem, if you don't resolve it in short order you may short the circuit breaker type fuse for the blower motor when it gets too wet. If your A/C suddenly looses 1-3 fan speeds, leaving you with max(4) only and your carpet is wet, it's most likely that fuse. The fuse is attached to the bottom of the blower, and about the size of a playing card. I had to fix this problem when I first bought my car...looked like somebody put some paper towels down to absorb the water and the wet paper towel tripped it, or it could have been the carpet itself.

[MickZEL]

Guys, and nobody tried to unscrew the bottom of the evaporator for further cleaning ?

[DaveTFL]

So glad I found this site. A lot of good info. I have had this problem and eventually the blower would slow down or completely stop. Toyota replaced the blower. Now about a year later these symptoms have returned. The blower started first by making a noise like it was hitting something. Also the classic sloshing noise on left turns, and the blower speed (was on 4) would slow and when I came out of the turn and going straight again would run again at high. Later the symptoms got worse and would also slow down when stopping or accelerating, as it did last year. Now the blower does not run at all. Occasional it would come on briefly at 4 with just a trickle of cold air coming out. Removed the drain hose and found that it was clear. Ran a tie-wrap up into the unit and no clogs has been found. Water does not drain. Perhaps it has already leaked out as the carpet and pad are saturated with water. Pulled up the carpeting on the passenger side to allow pad, etc to air dry. Could not find the circuit breaker fuse referred to by mazella. As I said I had this problem before and Toyota replaced the blower and all was well. Has this water backup damaged the blower again? Is the clog now gone? Ran the 8 inch cable tie the entire length into the unit without getting any water out. Other than having the dealer replace the blower, AGAIN, and handing Toyota more $ for this issue, any other suggestions?

I have no idea as to what Mazilla is talking about with the under carpet circuit breaker (unless it was something added by the prior owner of his car), as no Yaris has such a thing from the factory.

The blower resistor, which is a metal package with a 4 pin connector, is attached it the bottom of the blower housing. It has an internal fuse, which if blown will only allow the blower to run on the highest setting. If the fan will only run on high, then that fuse is blown and the blower resistor needs to be replaced.

If the fan will not run on any setting, including high, then the fan motor may be bad or either the 40A HTR fuse or the 10A GAUGE fuse may be blown.

I was talking about the blower resistor...I forgot it was attached to the blower and not the floor board directly behind it. It was the first day I got the car, sorry for the confusion. :)

[jward1366]

I went round and round with the toyota service manager about this same problem of water dripping from under the dash and soaking my carpet. He had the nerve to try and make me believe there was some sort of neglect on my part when this is clearly a Toyota defect. Seriously considering hiring a lawyer.

Water dripping onto carpet from passenger side is because the drain pipe is clogged with dirt or leaves. You need a thin piece of pull carpet back and slide the wire through the rubber hose. You will probably see water dump out on ground

[jward1366]

oh i know how to fix it i just resent fixin what toyota oughta be fixin

[bankrobber]

oh i know how to fix it i just resent fixin what toyota oughta be fixin
Got ya on that. Mine did it twice but out of warranty. I was parking under an Oak tree at my house but has not done it again. My last truck had same problem but had rubber floors so never fixed it. It use to get a puddle in the passenger floor lol.

[nopk]

Alright, so I'm having this problem too.

I've pulled off the drain hose, and I'm not seeing anything blocking it.

I tried sticking a wire into the air box it connects to, but it wouldn't go in.

I actually saw the condensation dripping from the white plastic components directly below the glove box.

Can anyone help?

For the record: I had my windshield replaced just before this happened. That could have had something to do with it? I had the windshield resealed and it's not leaking.

[Matthewces]

I had this problem last week. If your car is RHD just remove the carpet from under the passengers seat, and pull back the insulation from under the dash, you will see a black rubber pipe going from behind the dash to the floor. Now start squashing it so if the is sludge obstructing it, it just moves along, if you manage you'll hear the the water draining under the car. If this doesn't work you have to pull it out, BUT you have to keep your finger on the opening behind the dash or you will ruin your carpeting. Once you removed the pipe just blow compressed air though it until its clean. Then just assemble everything as it was. The longer you leave it not draining the more you risk ruining your compressor unit. IF you go to your dealer they will still charge you for the work (cause its a serviceable item thus not falling under warranty).

[nopk]

Scott de la CT sorted me out. I think I may have it working. I'll post if it did.

[maximapitko]

Same problem here. There is a TSB that calls for updated cowl (sp?) design available through the dealer.

[VTekFan33]

Looks like Toyota still hasn't fixed this issue! :eek:
I see most posts are for the '07 & '08 models. Mine is the '09 and I began having this issue yesterday.

Thank God for this site! I'm going to clean it out either today or tomorrow before it gets any nastier. Only good thing is that I have plastic floor mats down over my regular mats! :wink:

[painta176]

Ours is doing it too, followed everyone's advice and let it drain. It was easy to get to and only took 15 mins.
Take off the glove box by opening and squeezing both sides, pull back carpet from passenger footwell at the centre side of the car, you will see a short rubber hose. Pull it off both ends and put your finger over the hole.
blow the hose out, it gets blocked from road debris. Plug it back on and let the system drain. Job done.

[formulation]

I had an '08 LB and presently have a '10 4 dr LB. I installed the cabin air filter within a month of purchase on both vehicles. Never had a problem with either. (My daughter has the '08 now). Toyota should at the very least recommend the cabin filter. I keep manuals and maps in the glovebox, just no loose stuff (paper napkins, receipts, etc). I am not defending Toyota, but as with any vehicle you spend money for, you should research and know about the vehicle. YarisWorld has been an excellent source of information since my '08 was new (cabin air filter, intermittent wiper mod, etc).

[PennyNickledime]

Same thing here. Only, I bought the platinum warranty. So, I'm still covered. However, they are saying this isn't a "mechanical defect" and suggested I call my insurance agency and make a claim. I did so and they laughed in my face. I'm in the process of contacting higher ups to get this pushed through as a warranty fix.

I asked the mechanic if there was ANYTHING I could have done to prevent this clog from happening or to have caught it sooner. They told me there was NO way I would have known to check the air box and the only warning signs were the left turn noise and the water, which was what I brought it in on. If there is no routine maintenance to prevent it and there are no warning signs until full car flooding, then how is this not a manufacturers defect?

Jeep had a similar problem with their air boxes and had a recall. My dad had to have his taken in and they drilled a hole and put a valve midway through the line for added drainage.

All I know is someone in the warranty division is about to know me on a first name basis REAL soon. I am NOT paying 1500 bucks to have my car gutted and the entire interior replaced over some tiny clogged hose.

[stgillies]

Third time dealing with this same issue in my '07 Yaris hatch. First two times the nice guys at my garage fixed it from below--and it cost exactly $10 each time. Now that I have found this post I'll attempt the fix from the passenger footwell.

Anyone from Toyota reading this thread? If so, it would help if all readers would go ahead and add a "me too" message to let Toyota know how widespread this problem is. A recall would be in order--even if it's to add a cabin filter to unequipped vehicles.

[10Kyaris]

1) Lift up the carpets on the front passenger side of the car.
2) Disconnect rubber hose (top right hand corner) from the airbox.
3) Unplug rubber plug in the bottom of the car (underneath the carpet) to allow water to drain
4) Stick a hanger or stiff piece of wire into the hole in the airbox (and shake it all about)

Only took a few minutes to do.

I have pictures if someone would like to see what the hose looks like (this site needs a file area?).

Much simpler than accessing it from underneath the car.

Much cheaper than the dealers who quoted about $300 to do it (said they needed to rip everything out).

The dealers also claimed they'd never seen this problem before.

The smell seems to be mold or something from the airbox/carpet... and starts to disappear after the car has dried out.

I'm really disappointed by the Toyota response. This is obviously a common problem which they should be able to diagnose on the spot.

The solution is probably to fit a larger hose and/or to provide easy access to clean the airbox.

This is a manufacturing issue... and Toyota should address it.

Thanks very much to those who posted information which helped to diagnose this problem.

:-)
i could use those pictures.. thanks

[arizonabay]

I had the same problem explained here happen to me twice on my '07 3 door. The first time I brought it to the dealer for regular service they said it was common and they blew the drainage hose out with an air compressor. It was fine for about 8 months but then it happened again. I found the hose and cleared it myself and everything is ok again.

the dealer also suggested using Lysol to spray the carpet to prevent mildewing if it gets soaked. I pulled back all of the carpet and doused the floor mats and the area underneath the floorboard carpet with the lysol after drying (styrofoam looking stuff) and the smell went away rather quickly. This has been the only issue I have had with this car and considering how easy it is to fix I don't see it as a major deal. However, it would be nice if Toyota would acknowledge it and issue a recall.

[DoWhatisRightToyota]

Simply put, me too.

Leaking onto the floorboards, creating mold and headaches. Car has less than 7k miles on it, this is a complete design flaw and should be addressed as such by Toyota.

A CLASS ACTION LAWSUIT may be the way to go. This problem has existed and persisted now on FOUR different years and models of the Yaris.

I have a friend with the same exact 2010 Yaris as mine, and had the exact problem about a month ago, only her AC got fried in the process. Her dealership installed some mesh grating up under the windshield cowel to block larger debris. My dealership only offered to unblock and clean the drain (full warranty), and charge me $40 for an air filter. I declined the slap in the face and will opt to do it myself after I pick it up this afternoon.

I am filing a complaint here: https://www-odi.nhtsa.dot.gov/VehicleComplaint/index.xhtml
And I am on board with anyone else who would like to join efforts to force Toyota to acknowledge their flaws in design, and own up to it. My family is a faithful Toyota family, however this incident could surely break that loyalty.

Do what is right, Toyota!!!

[NHYO]

I have the same problem on my 07 Yaris.

Followed the instructions very helpfully given on this forum and pulled the carpet back on the front passenger side of the car to reveal a totally loose rubber hose and the exit hole on the bodywork exposed!

I am guessing the hose is not normally held in place by the carpet, so it didn't "come off" when I pulled the carpet back. Is the hose supposed to be held in place with a special clip or sealant, etc? Any advice would be greatly appreciated.

BTW, when I called the local Toyota garage about the soaking set footwell, they wanted to charge £50 just to diagnose what is wrong!

[Ozziespur]

It's obviously an international issue as we in Australia are experiencing the same problem. And yes Toyota here are towing the company line and saying it's not a manufacturing defect. Didn't even bother getting a quote from Toyota to fix it as I'll do it myself (this afternoon) when the wife gets home. Very disappointing Toyota as we are a Toyota family too and have been for a few cars (each) now ......

[drodrey]

yep definitely an international problem. I'm Australian and have an '07 Yaris. First had the problem about 6 months ago and my mechanic fixed it for about $50 from below. Now happening again, but the sound is much much louder than last time so I'm worried it's worse. I'm going to try and fix it in the morning.

[Babs2yz]

I am having the same problem with my 08 Yaris. Is there a class action yet?

[TMR3]

Seems like it is also occuring with earlier models.
I have a 01/2006 model yaris and i currently have just started to notice the same problem.
Ive done everything suggested on the topic but nothing has currently worked.
anyone know how much it will cost to clean out the whole air con system in AUS?

UPDATE:
i had taken my yaris to my mechanic and he said he would go through everything to find the problem.
NOTE: i did clean out the small little tube on the right corner of the passenger side and still nothing has happened.
My mechanic rung me 3 hours later saying he found nothing wrong and didnt charge me for the labour. He was confused himself too - never seen such a thing.

anyone care to help me? Im on a tight budget and would really love to know how to get this mouldy smell and a wet carpet out of my car.

TMR3

[canisestinvia]

Just wanted to say thanks to this thread and forum for providing me the fix for this issue. I think maybe 3 pints came pouring out of the hose after I wriggled it some.

[pandadiana]

Hi I have the same problem. I have a 2008 Toyota Yaris. My AC has completely stopped working at this point. How do I go about adding myself to the complaint list. Toyota needs to do a recall on this and replace our ACs ...this isn't fair.

[niktracey]

We have a 2008 Yaris and were having the same issues as have been described, noise during a left turn, leakage onto the carpet and mat. My husband pulled back the carpet and found the hose but until he inserted a wire to clear it out, nothing would drain. After the wire pulled out debris, we drained about a gallon of water. So far, so good. The noise stopped immediately as did the leaking. We just have a wet, stinky carpet to deal with at this point. Thanks to this forum, and the users, for the help!!

Just make sure you install a cabin air filter (in the slot behind the passenger glove box) to prevent it from recurring.

[sirlark]

South African Yaris T3 owner here. For me though, the difference is that water is not leaking in through the grommet, but from somewhere up behind the upper passenger glovebox. I've tried having a friend run the hose pipe over the windscreen, but that doesn't cause water to come through, and I checked that the water is being funnelled out to the underside of the car, which it is. I peeled back the carpeting and found the gromet which was still in place while this was happening.

BUT, just make certain I'm getting things right... I have a right-hand drive vehicle. My passenger well is on the left side, and the grommet I examined was also on the left side of the well, i.e. the outer side? I couldn't see it very well, and it felt more like electric cable going through than piping... I think I might have the wrong side of the well...

[Joker4274]

I do have the same issue with my 07 Yaris I took for the car to Northridge Toyota ;The third time for the issue describe above on June 5th 2009 They want to charge me because my car is over 52,000, my warranty is up and they told me it would be charge to diagnostic the same issue on the car has been repaired under the warranty twice.I declined,and
I escalated to Toyota Motors They get in the same position as the dealers saying the following : The dealership determined that the failure was not a factory defect rather it is a customer related problem. Mr XX is leaving his car in a unprotected area. The drain hoses for the a/c on his Yaris are being plugged by foriegn debris causing the water to back up in the evaporator and is causing the leak into his vehicle. He was told on both occassions that this is not a warrantable issue outside influences are not covered by Toyota. On his two previous appointments the debris was cleaned out of his vehicle as a Goodwill gesture from Northridge Toyota and the Factory. He has complained to Toyota Motor Sales and Toyota has turned him down for any Warranty assistance. Mr XX Yaris is now out of the Factory Warranty. Knowing that I went to different Dealership : Thanks to service Advisor and his mechanic explained me the issue why it get debris inside the a/c box I understood clearly is a manufacturer issue because if you put anything in your glove compartment when you have the A/C button in circulation mode the A/C Box sucks air inside of the box causing with the time the drain plug be clogged and the fluid will leak inside the passenger side under the carpet.In order the A/C drain plug don't get clogged you can't put anything inside the glove compartment.
This is Lemon issue affecting most of the Toyota Yaris Hatchback 07-up
If you guys get the same issue as my self hit me up for legal referal against Toyota Motors.
Regards
Tenaz
Pd: I'll keep you update.

Tenaz I can relate to the same issue as you, I just recent had the same issue with my wife's 2008 Yaris. I got it unclogged but in the progress of getting it taken care of I think it has messed up the blower motor or transistor one as well. It dosen't drain in the floorboard on the passenger side anymore, but now when you turn it on high the blower blows for a few minutes and then dosen't blow at all. I will appreciate any legal information you can give me on this if there is a ongoing action going on against it.

[VICKY_K]

I am having exactly same problem - this is the 2nd time it happened -
first time we had big rain for days and I started noticing the noise when turning, water in the passenger side, etc .. all the same...(when the AC was on) -- reading info I found about cleaning the A/C draining hose( that should drain to the street under the car) --I did the cleaning and got lot of water out..
--problem stopped for 3 months. :eek:More rain and...same thing again..
I did the cleaning - got water out - but I noticed that still is leaking when the AC is running - by the way I empty the glove compartment since the first time happend.. I read it in a forum.
Just this morning I took it to Toyota (with warranty) and the guy told me they know exactly what is the problem but toyota does not have a recall for this problem. After waiting 1 hr, he came back saying it will take longer than expected, because they need to dry all the carpets, etc .. and they gave me a rental car while they work on mine! Toyota pays for the rental, but no for insurance.
I am/was :mad: a Toyota buyer !!!! but this is Huge let down - disappointment - they know this a known problem and they should make a recall and fix all Yaris!!!
I will appreciate any information on this if there is a ongoing action going on against toyota.
THANKS - I will write about my "fix" and will try to get information on what exactly they replaced.

Did you or they install a "cabin air filter" in the slot behind the glove box? If not, then it will just keep occurring, as that filter is key to prevent airborne debris from entering and plugging up the airbox.

[Scooterpoot]

Just finished addressing this issue myself. It looks like the drain was plugged at the air box where the rubber drain tube attaches. After sticking a heavy wire into the drain opening an amount of water and gunk poured out. I used a plastic bottle with tubing attached and filled with water to flush the bottom of the air box. Just put the end of the tube into the drain opening and squeeze. More gunk that looked like mold poured out. After flushing several times I finished with with a solution of bleach and water. If you do something like this make sure you pull the carpet back and use a towel to catch the water that drains out. I'll install a cabin air filter tomorrow and hopefully that will be the end of it.

Props to everyone on this forum who has provided solutions and insight to this issue as well as many others :thumbup:.

[skysos]

Got a similar response from Fremont Toyota at the Auto Mall. The service guy was arrogant and not helpful at all. The car was 1-month and 2000 miles out of warrantee. I will never go to those guys again I've owned 7 toyotas and this may be my last one. There are lots of reliable options out there -- why would I want to take a chance on them again?

I hope there is some recall issued for this. The car is going to my son and I don't want him to have to deal with this.

[DonM]

I have a 2008 Sedan and fortunately, I have not had this problem crop up yet but I am wondering (feel free to correct me I am wrong) if this would not work.........using a wet/dry shop vac - insert the hose that is located in the passenger seat floor area into the hose of the shop vac and turn it on - would it not be able to suction out the blockage and the water?

[jameseddy]

2008 had same problem $1700 repair

[Steveh27]

Today my 2010 with only 16,000 miles and still in warranty started making a sloshing noise. When I got home the passenger floor matt was soaked. I took it out & put a towel in to catch drips. I have an appointment with the dealer tomorrow & they already said it wouldn't be covered if it was just debris blocking it.

I just found the black tube & squeezed it from the top to the bottom. Water is draining out from the bottom of the car now. Do I need to remove it & try to clean it out more & the area above where it is attached? Should I still go for the appointment? I do need to go in for the oil change.

CTScott I have had the cabin air filter for 2 years & here we are.

What came out of the hose that was keeping the water from draining?

[Steveh27]

I did not detach either end of the hose. I just started squeezing it at the top & worked my way down, numerous times. Almost like milking it maybe. I did not feel any obstruction. Perhaps the pressure just forced something out. The water drained under the car & I didn't see any obvious debris in the brief look I made. It could have been a pint or 2. I wonder if I should remove the tube to see if it needs further cleaning? And then try to check if there is debris above the upper hose attachment?

You may have actually just pushed the obstruction up and temporarily out of the way or it may simply have been a clump of pollen or mold that broken up and flowed out with the water. The cabin filter helps immensely, but it is not an absolute fix, as some particulate does pass through it. Also, frequently running an AC system on recirculate will tend to grow molds in the airbox.

[Steveh27]

So you think I have to detach the hose? If so, does it just pull out, twist out, pop off, unscrew or ??? Or what else should I do? I think this may have been the first leakage on the mat.

Thanks.

So you think I have to detach the hose? If so, does it just pull out, twist out, pop off, unscrew or ??? Or what else should I do? I think this may have been the first leakage on the mat.

Thanks.

It just pulls off, but you can also just go up the hose with a large cable tie.

Does this hose drain the water coming in the vents below the windshield? My 2010 has fine mesh screening the debris from going in there.

Does it also drain the AC condensate?

I'll pull it off & check in a bit.

The hose only drains the condensate. The vents by the windshield drain to the wiper tray. The air entering the A/C system goes down through those holes, back up and then straight back through the firewall. That path keeps water from entering.

Thanks CTScott. I'm at the dealer right now. They're doing the oil change & will check to make sure the bottom of the hose drain is clear & will show me where that is.

[Steveh27]

The dealer said there were many spider webs under the car & that 1 one of them may have gotten in the drain & been the clog. They did clean it out from the bottom - no charge with the oil change.

That makes sense as I've had the cabin filter for 2 years to prevent stuff getting sucked into the airbox.

They said to wash off the bottom of the car frequently to keep the spiders down.

Interesting. I wouldn't have thought of little critters going in the out door.

I have the 2005 hatch, and have the same issue of water draining over the front passengers feet.... It only started after driving through deep pools of water along a rural highway, during a very heavy rain storm a year ago... It's been happening every time after a storm since then, so i'm not sure whether the car may have some additional water collecting internally from the rainfall?

Thoughts?

I'm keen to try clearing the hose though, and see if it helps next time it happens.

1) Lift up the carpets on the front passenger side of the car.
2) Disconnect rubber hose (top right hand corner) from the airbox.
3) Unplug rubber plug in the bottom of the car (underneath the carpet) to allow water to drain
4) Stick a hanger or stiff piece of wire into the hole in the airbox (and shake it all about)

Only took a few minutes to do.

I have pictures if someone would like to see what the hose looks like (this site needs a file area?).

Much simpler than accessing it from underneath the car.

Much cheaper than the dealers who quoted about $300 to do it (said they needed to rip everything out).

The dealers also claimed they'd never seen this problem before.

The smell seems to be mold or something from the airbox/carpet... and starts to disappear after the car has dried out.


I'm really disappointed by the Toyota response. This is obviously a common problem which they should be able to diagnose on the spot.

The solution is probably to fit a larger hose and/or to provide easy access to clean the airbox.

This is a manufacturing issue... and Toyota should address it.

Thanks very much to those who posted information which helped to diagnose this problem.

:-)


Please sent me photo of the hose. The carpet was hard to remove, do you just tear it out? Thanks.

Hello all, i am very excited to say i just fixed the water leaking from under the dashboard on the passenger side. I called up toyota 2 days ago with my problem and was told it would be an all day job and they would have to remove my dashboard (would cost around $400) They said my air con was blocked and was causing all the water to leak into my heater box and then run onto the floor. Well i thought that sounded like BS and so decided to google the problem and found many people with the same issue. The solution is simple.

Under the dash on the passenger side, pull back the flap of carpet a little bit and on the right hand side, down low, there is a little black soft tube that is leading to the outside of the car. Just pull on it and it will easily pop out. Dont worry it will pop back in afterwards. Then get a stick or something flexible and stick it up the tube being gentle. Water will run out when you have unblocked it. then plug it back in and the problem is fixed. No more water on your floor. I am a 28 year old girl with no expereince in cars and i fixed it so dont go to Toyota for this problem and save yourself $400. Good luck everyone. Hope this helps all with the same annoying problem. :)

How was the carpet held down, when I try to pull back, it was very restricted. I did not go any further from here. Was it velcroed? Thanks.

There is a piece of velcro that holds the corner in place. You only have to pull it back a couple of inches to access the hose.

hi there every one anybodyb know how to take the bottom half of the air box out, so I can have a proper look.

To remove the bottom of the airbox you have to remove the entire dashboard, the metal support for the dash, and then the airbox itself. It may be easier to go into the air intake for the fan with an inspection camera if you want to take a look.

Hi, ive been reading this thread as I too have an issue with water in the passenger side floorwell front and back. I am not sure if it is my AC unit as over here in the UK we rarley use aircon and my outlet drain hose looks to be clear. I have had a piece of stiff wire in the hose and it went up to the AC unit without much resistance. I wasnt sure how far to force the wire as i am not sure if I will damage something.

Also my air blows with quite a bit of force through the drain pipe when the heater is on so I am asuming the drain hose is not blocked.

The amount of water that is coming into the passenger side of the car is quite a bit, I often have a good half inch in the rear passenger well. I am suspecting its rain coming in somewhere!!!

Does anybody know any suspect places for water to get in on the 2005 Yaris models?

Thanks for your help on this one.
Mud :help:

There are a few threads on this issue. The condensate drain hose is plugged, causing the backup. This is very common in the spring when the trees drop all of their stuff.

You can clear it yourself using something like a tiewrap (flexible plastic item). Gently insert it into the condensate tube from under the car, and the water should come gushing out.

Thanks for the tip; cleared hose with a wire hangar and here comes the water. Problem seems resolved though air is rushing in and out (not steady). Going to monitor for a few days.

Just wanted to say thanks for the tip :thumbsup:

[grumpstain]

Hey guys first time poster here. Just wanted to say that just popping off the drain hose and taking a shop vac to it for less than a second did the trick of loosening the blockage, then just drained it into a pot.

I know some people think it's annoying, but it's a very quick fix if you've got a shop vac or something with similar suction. Better than poking the blockage back up into the hose.

[Yaristrocrat]

Not really adding anything new to the discussion, but I wanted to say "Thanks" to everyone for your instructions and photos on how to deal with this problem. I just experienced it for the first time today, and using the info in this thread, I believe I've corrected the problem. I unplugged the hose and ran a hanger into it, then the water flowed forth. I plugged the hose back in and a nice pool of water soon formed under my little Bayou Blue pal. We shall see how things progress in the next few days.

Again, thanks for the help! :thumbup:

[jack black]

looks like my kid has a problem with this. i instructed her not to use AC or fan and avoid sharp left turns. will try a wet vac after work.
scott's picture is very helpful: http://www.yarisworld.com/forums/showpost.php?p=355106&postcount=22

edit: the wet vac did nothing. i also probed and removed the rubber drain hose, no water or obstruction. where is the water coming from?

[jack black]

OK, i learned about this TSB 027-08:
http://workshop-manuals.com/toyota/yaris/l4-1.5l_%281nz-fe%29/body_and_frame/exterior_moulding/trim/cowl_moulding/trim/system_information/technical_service_bulletins/all_technical_service_bulletins_for_cowl_moulding/trim/sb0027-08r1/jan/10/a/c_water_leaks_onto_front_or_rear_carpet/

the fix is a new cowl panel (55708-52170) "to help prevent debris from entering the HVAC unit".
but i have a filter already, why would debris enter AC?

anyhow, has anyone done that new cowl panel fix?

BTW, the lowest i can find is $158 (before S&H) for that large piece of plastic. is it worth?

[CTScott]

With the filter in place the cowl update is really not necessary. It would just reduce the larger particulate captured by the filter.
