Climate control bulb

[vinny121]

Hi, Do you know how to take apart the climate control knob and replace the bulb? I not sure which clip to remove and the Toyota service manual appears to be no help. I was thinking of purchasing the entire A/C panel assembly with the bulbs to make this easier but I am not sure. I have 2 bulbs out on my A/C panel upper right (outer ring) and the lower knob (outer ring). Pictures are attached. Thanks! I have the Sedan with 105K miles.

The bulb is mounted to the rear of the knob. You will see a small round area with a flat indentation in the middle. You simply turn it a quarter of a turn with a flat blade screwdriver to release it.

My bulb appears to be out on my climate control knob (the temperature knob with the blue/red zones), too. The other two knobs light up perfectly, and everything is working fine, so I don't think it's a fuse. Is the correct replacement bulb part number 9001001113? I have a 2009 Yaris. Thanks!

That is the correct part number.

The recessed area in the center is where the bulb is located. 1/4 turn with a flat head screwdriver releases it.

And, this is what the bulb assembly looks like when removed:

CTScott, thank you. I suppose it's not accessible by simply pulling the knob off...??? I bet the entire panel must come off...!!!

Correct. The bulb is on the rear and to access it you must remove the entire control panel. That requires removing the vertical pieces along side of the radio (by simply getting your fingers behind and pulling), removing the radio trim (again just pulling), and then pulling the AC control panel off.

Last question. No screws to remove first? Just start by pulling panels? Thank you.

Correct.

Got it...thanks a lot.

Thanks all for your help. For the sedan, I had to remove the 4 black screws around the radio to get access to the AC control panel. Thanks for the pics of where the bulb is located. For the climate control knob, it is not obvious which clips to separate to get access to the bulb. Any ideas?

Yes - The sedan with the integrated radio does require removing screws to get the radio face (or in that case the entire radio) loose.

For the knobs, you just need to release the cable assembly from the back of the knob. You really don't need to remove the entire knob from the panel. People often break the little mounting tabs when doing so, as there are four tabs on the knob assembly that click into four slots on the panel, and the panel is very brittle, so it is easy to break the slots.

thanks, this post has helped me loads, can I ask, this green bulb.. can it be replaced with different colours? as I have replaced the head unit, its lights are orange/red and the climate control are green, I'm hoping to match them up.

The green is just a sleeve on the bulb. I am not sure if you can find the bulb with other color sleeves, but you may be able to find replacement LED bulbs of that same mounting.

is it a T3 or a T4.7 that go in there?

Actually T4 (AKA Neo-wedge Type B).

Here is the thread I mentioned above:

I'm not mechanically inclined (I've only ever replaced spark plugs, batteries and headlight bulbs on other cars) and the bulb in the temperature control A/C knob is burned in my newly purchased 2013 5 door liftback. It's not a huge deal because at night I can just feel for the little indicator divot to see where the temp is at, but I was wondering how much would be a reasonable charge to have these bulbs replaced in the future by a professional.

I can generally follow step by step directions fine, but I'm nervous about breaking one of the plastic clips...and taking things apart and putting them back together just as they were isn't a forte of mine in general.

It'd probably be best to change all three if I do end up having it done I'm guessing.

Also, they're LED bulbs which are generally supposed to last longer than the life of a car, so is there a reason it burned in the first place and seems to be an issue that a number of people have in this part of the Yaris?

[KingForADay]

I should add that I noticed today that the orange A/C indicator light works on that knob, it's the temperature indicators that I can't see at night on the same knob. So I'm not sure if it's the bulb or what anymore.

[CTScott]

It is a separate little tiny bulb. There are a few threads on here with pictures of what they look like and how to change them on a 2nd gen Yaris. For your 3rd gen it would be basically the same. There are LED replacements for them and I believe there is a thread on here with LED bulb info that also lists them.

Thanks very much for the info CTScott. I'm not mechanically inclined so what do you estimate would be a reasonable charge for a mechanic to replace all 3 bulbs with LED lights that I would supply?

It should only take one a couple of minutes, but they would likely hit you with a minimum charge (30 minutes or so).

Great, thanks so much for the info!

Is It the same for 2010 model? My central knob is the only one not working..

How can I change the Rear Defroster light bulb? I want to change to a different color and have the controls all pulled apart, just cant figure out how to disassemble the switch to get to the rear defroster light bulb???

[spookybathtub]

I changed my lights for amber LEDs to match the display of my ham radio. I prefer the amber overall. But one downside I hadn't considered: The blue half of the temperature knob goes completely dark, since it filters out all the amber. So I left that one green. These are the LEDs I bought. If I did it again, I would choose a brighter one, because these are a bit dimmer than stock.

I must have broken something while doing this mod. Now the fan only works on setting 1. When I try 2, 3, or 4, I hear a click and the blower stops. I'll have to open it up again this weekend; hopefully it's nothing major.

I know it’s been a couple years since anyone posted in this thread, but I have a 2012 Yaris sedan and I only have one of the climate control dials lit up because the other two burned out. I saw the T4 T4.2 NEO Wedge LED lights on eBay. Will they still work?

[scott4banger]

The process ct scott commented on works with the 2013 dash layout too also same t4 bulb. 😀

Hi

I have just bought my 2015 Yaris Sport and my climate control panel only has one outside bulb working (the press button ones do)

I am like Wreck it Raplh when it comes to repairs, is it easy to do this myself and how does the panel come off please.

Sorry for sounding hopeless, need to know where to get bulbs also, is ebay ok

Thanks for the help

For future reference I have confirmed that at least the 2009-2013 corolla bulbs match. I’m sure many other Toyota’s match too. I didn’t want to pay for new bulbs and instead went to the junkyard and pulled them out of the corolla, saving me a few dollars.
