Air Conditioner Noise & Leak?

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.

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.

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.

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/sho...6&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?

OK, i learned about this TSB 027-08:

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.
