I have not found the sensor yet. I looked under the passenger side dash and drivers side dash and took out climate control unit and found nothing. In the ceiling above the drivers head is a small 2 inch round vent or something like that. That might be the sensor. I need some time to investigate that.
Thanks for answering.

Just recently bought an 07, and the salesman indicated that the sensor is the little thing in the ceiling above the drivers head.

I have to figure out how to get at it without tearing out the whole ceiling. I tried to pll that round thing off but did not want to break it.
Thank you.

Here's the instructions from the service manual (2007)
- remove the left windshield garnish molding
- remove the left center pillar assist handle
- remove the center pillar garnish molding
- remove the left sunshade
- gently pull down the headliner
- disconnect the electrical connector from the inside air temperature sensor
- partially remove the inside air temp sensor from the headliner
- remove the sensor grille from the inside air temp sensor
- remove the inside air temp sensor from the headliner

Thank you very much. It sounds like I would have been at it for awhile trying to figure out how to do it. This is a big help.

I went to a Chevy dealer and he thought the control itself is bad. He also said that there might be some software updates that could bring it up too date and make it work better because of a glitch in the control.

2008 TAHOE LT A/C PROBLEMS by whiteelephant

Hi, folks. My wife and I purchased a new 08 Tahoe LT on Nov. 2nd. Five days later, the 2 vents on the passenger side start blowing hot air. Also, the air is not as strong on the 2 right passenger vents. I took it back to the dealer, they re-set the system and couldn't find anything wrong. When I went to pick it up after starting it up at the parking lot, the problem was still there. I left it overnight again, they supposedly reset the system to "08 specs" and said the vehicle was ready.
 
When I went to start the vehicle to take it home for the second time, lo-and-behold, the problem was still there. Needless to say, this has been a very stressful week for us. The vehicle broke-down less than a week into ownership.
 
I spoke with the new car sales manager, the service manager, and the customer relations manager. They supposedly got with GM and GM informed them this is a "common" problem that has been reported in several 08 Tahoes and there is no "official" service bulletin for a repair yet.
 
I'm very frustrated, and by Texas Lemon Laws these people have 3 attempts to fix the same problem. This is now their 3rd attempt. Of course everyone at the dealership is your best friend until you actually purchase the vehicle and sign the dotted line.
 
I've read similar instances on 07 models but no results. Anyone here have any suggestions???
 
Thanks in advance for your attention.

Wow. Sorry about your problem. You mentioned that the vehicle has a climate control problem and you say that the vehicle "broke down". Are there two different problems with your Tahoe? I have an '06 Tahoe with no problems like you describe.
 
But to address your issue, you might want to try a different dealer if it is conveniant for you. Also, since you just bought it, have you asked if they would exchange it for a different vehicle on the lot?
 
Good luck and please let us know how it turned out.
