Climate Control Help!

So like many of you have run into and I the same, the light bulb on the passenger side of the climate control cluster had burned out. I have a 2007 Tacoma. I order the 10 pack of bulbs online thanks to another post on here and was able to easily replace the bulb. Upon putting the cluster back in place, I realized I had lost my ability to change the temperature per the dial.

I can rotate the dial easily like before. I can change the fan speed just like before. I can also still change where I want the fans to be blowing (feet, face&feet, defrost, etc). All I seem to get is Vent air though. No Hot air, no cold air, no AC.

Seems odd as the only thing I did was change a light bulb and was very careful about it.

Any ideas? Is there a major fuse or relay that would dictate the entire temperature range? Thanks for the help!

 

So have you found out what the proplem was???is??? I am having the same proplem...it blows but no heat comes out the ac works but no heat...i have checked the fuse..it is good...not sure what to check next..I am trying to avoid taking it to the dealer..any help would be GREATLY APPERCIATED...

 

I will dig into it this weekend and report back here what I find.

Anyone else?!

 

Very Cool....We will let you know if we find anything out...See what happened with our truck is the A/C stopped working..then just started to work again...now the heater has done the same, it didnt work, then it did for a day, now its out again??? ..the light on the left controller is also out but we have not replaced it..this all started after we had a brake controller installed...the shop that did the installation says its nothing they did...so now its starting to get cold out and we need to get this fixed...and you know how the dealerships are......want to try and avoid them..thanks

 

bump. i’m trying to fix mine. i also have ’07. everything work. but the far right bulb is out. where/how do i get to the bulb? right now i have everything but the circuit board out.

edit: i found the 2 main round bulbs. how many are their in total on it?

 

Just those two

 

ok so i had to put it back in. and now the fan speed dose not want to work like it should. the HI and that one just below it, only work if i hit it.

 

CMCATTACK......DID Y0U EVER FIND OUT WHAT THE PROPLEM WAS???? I AM AT THE DEALERSHIP GETTING THE OIL CHANGED ...GOT A FREE COUPON OTHERWISE WE WOULD HAVE DONE IT OUR SELVES.... ANYWAYS I DID ALOT OF RESEARCH AND IT SOUNDS LIKE IT MIGHT BE THE BLEND MOTOR DOOR....06 TO 09 ARE KNOWN TO HAVE THE PROPLEM AND I HAVE FOUND A FEW PEOPLE WITH 06,S HAVEING THE SAME ISSUE....SO I AM GOING TO BITE THE BULLET AND HAVE TOYOTA CHECK ALL THE FUSES FREE OF CHARGE THEN PAY 120$ FOR THEM TO TELL ME IF THE BLEND DOOR IS THE ISSUE....i WILL LET YOU KNOW WHAT i FIND OUT ..IF YOU COULD PLEASE DO THE SAME THAT WOULD BE GREAT........THANKS

 

Did or do you have what looks to be a wet spot on your passenger floor mat?

 

My problem happened to be that when I replaced the light bulb, the temperature dial mechanism came somewhat disconnected from the circuit board in the temperature cluster. There were two little metal clips that had come out and I had to re seat them. Hope this helps someone in the future.

 

ok cool. i have to see if their is something like that but for the fan speed.

 

Did you ever figure out the fan speed issue? I just changed my bulb out and now the fan speed spins freely in place. It doesn't want to click anymore. Any help would be appreciated

 

Same thing happened to me. Make sure the little red ball is tucked inside its hole against the spring. Hope this helps.
