The ambient air sensor is probably bad, which is a common failure. It is fastened to a plastic air dam behind the radiator, and really easy to get at/replace. IIRC it is only visible if you look up from underneath the car though. It is GM p/n 10248414 and costs ~$10 from the dealership.
I had to replace it in my wife's old car (1999 Olds Intrigue). The climate control unit said the outside temp was 34*F in the middle of summer and would not allow the A/C to come on because the ambient air temp was bad and indicating a false reading. The A/C compressor isn't supposed to engage if that temp reading is below a certain temp (usually 40*F).
