Re: Another Temp Control Question
Check for dust in the sensor in the dash just right of the steering wheel. There's a small screen looking area where it's located. You can clean it with a soft brush or small vacuum cleaner attachment.
There could be something wrong with the controller itself. Someone with a Tech II, or similar scan tool could help to find out if that's the problem.
