I noticed today that when I pressed the A/C button with the auto control, it just blinked 3 times. The outside temp was 20F, so I don't know if that was the reason. I also noticed a similar issue with the recirculate button. I tried pressing it, and it just blinked 3 times and would not go on.
cfedor and goldenclave hit it on the head. Evap coil. $2k. Good news is that it is covered under some warranty that came with the car. Had no idea I had it. I spent last night preparing a missive I was going to fire off to GM looking for some relief on a $2k repair to a car less than 5 years old with less than 60k miles.
Anyway, thanks for the guidance. The contributors here are an invaluable resource.

Sad to read about A/C evaporator coils needing to be replaced. Have a 2008 with 95K miles on it and A/c seems to be fine. I wonder if those that use AUTO MODE rather than MANUAL MODE have a higher rate of failure on these coils. I never use AUTO mode as it seems to run the compressor significantly more than manual mode. Not sure there is any correlation here or not. Comments?
Ive wondered the same thing...
I rarely use my AC.
It was 105 in my neck of the woods yesterday. No AC. As long as air is flowing- its good enough for me.
On the way home- I hit heavy traffic on the freeway- crawling along... I hit the instant update- temp showed up as 116.
Still no AC.
Though once home- I picked up mom--- I turned AC on for her....
