Hey all, I have searched about this and only found threads regarding the a/c light flashing. In which I already had this problem before so I know it't not that. But why won't my green a/c light come on at all anymore? Could it be burnt out? I tried checking to see if I was getting any cold air but its hard to guess. Considering the air outside is still somewhat cold and it could just be that coming through the vents. Maybe, I need my a/c recharged? Anyone have any guesses to why the light doesn't come on? Thanks in advance.

the bulb could simply be burnt out....like stated above check and see iof the compressor comes on...the indicator bulbs do burn out over time, but it doesnt affect performance of the function they control....the bulb is also easy to replace too

Is the green LED for the A/C button easy to replace? Its the one when you push the button in. I thought that one is soldered into place? I hope thats the problem because last time I used my A/C in like September it was working fine.

If it's cold outside you can still test your A/C. Switch to recycled air and turn on the heat until your car is warm. Once your car is nice and warm, turn on your A/C and turn the tempature switch to cool. If your a/c is working, the car should start recycling cold air. This will help you determine whether your a/c is working or not, or is it just a simple light bulb issue

pull out the HVAC controls and do a bulb switcharoo.. takes 2 mins
Your'e misunderstanding which bulb it is. The bulbs that you are talking about are the ones that light up the ring of the controls (red circle in pic) Yes, those are easy to replace but those are working. The one that is not working on mine is the green light when pushing in the A/C button (red arrow in pic) If it is that bulb that is out it seems a lot harder to replace. The bulb is behind the button and looks soldered into place.

the a/c light is led, shouldn't go out that quickly. and yes, its soldered in, and no its not easy to replace. like the others said, check the compressor and make sure your a/c actually works.

for future reference, all the button lights and symbol back lighting (Recirculate, A/C, Defrost) are leds, the outer rings are incandescent bulbs. i've replaced those leds to blue and red, and its not easy. took a little tinkering around to figure out how to get them apart.

if it is indeed the LED thats out, i have a spare gen 5 hvac controls... i'll post up a diy this weekend if you need it.

Is the compressor underneath the alternator? How exactly do I check to see if it works? Can you distincivley hear it when the engine is running?

Would the light really have anything to do with not coming on if the compressor or another part of a/c system is not working?

Did you read my post? Why don't you do a simple test to see if your ac is working or not.

Let us know what it was.

My buddies' went out not too long ago and his was just the bulb. Hopefully that is the case for you because that is the cheapest route.

How did he go about replacing it? Did he do it himself or have the dealership do it or someone else?

^^ Update: brought it in to toyota this morning and they diagnosed the problem. Somehow my A/C fuse behind the panel was missing. It wasn't blown. It was completely missing. Real weird! I was tinkering around with my head unit the other day because I had to remove my sirius and ipod interface adapter so it could of happened then but I never distinctively took them out. To bad I couldn't figure out the problem myself and had to pay toyota $60 to figure it out. I should have thought of that before that it could of just been a fuse. DUH! But oh well, im just happy that it's not a major problem. Thanks for everyones advice and input though.
