The one with the digital temp display and fan speed etc. and the round knobs that u can set seperate driver or pass side temps. Not the one with the slider for driver and pass. I don't believe they have auto climate control.

What I am getting at is maybe it is a faulty temp probe for the driverside. Or a faulty controller. I have never had these apart but a friend had a similar problem in a Denali and that is how he said it was explained to him as to how the system determined what temp each side was at. In Auto, it would do the same thing but I do not remember what it was for sure. For no reason it would get hot when he had it set at 75. But just on one side.

I think i may take it to the dealer today when i get back from sarasota but do u think i need to take my efi live tune out incase they want to keep it overnight. Last time they reflashed the truck and put a 06 upgrade in it and my truck smoked like crazy and got really bad fuel miliage. So im thinking they may do another reflash even if i tell them not to
