Outside temperature readout way off...
It was 107º here today. I was out driving around for about half an hour and the outside temp on the AC screen never went over 87º. It's been pretty accurate until today. Is there a button push sequence on the AC control that will reset or recalibrate it or maybe the sensor under the hood is bad?

I went through the same with inaccurate outside temp readings. Tried to calibrate several times, finally just had the outside sensor replaced by the dealer. Problem solved.

Simultaneously, depress the far right two buttons and the fan up button on your climate control.
I did this several times to no avail. I believe GM has a bad batch of sensors. It took about 5 minutes to replace and no costs, if you still have warranty.
A better description of buttons:
Rear Defrost (right most climate button)
Front Defog (2nd right most button)
Fan Speed Increase (4th right most button)
Must press all three at the same time.

So if you press the above buttons and the display is way off on the actual temperture, you have a bad outside temp sensor.
