A/C turning on my itself, even during winter time. Now my A/C isn't cooling like it should. Sometimes it blows cold and sometimes it just blows warm air. I have to turn the A/C off and back on several times and turn the thermostat from cold to hot and back several times to get it to blow cold air. The fan sometimes blows hard and sometimes you have to turn it all the way up to get it to blow any air at all.
CURRENTLY IN SHOP WAITING ON CHEVROLET BACK OPDER FOR A/C PROBLEM
Not going off however, I have had issues with ac shutting down. Dealer stated didn't know where to start. Been 3 times. Now they say Chevrolet has a national back order on the compressor, and doesn't know when they will be released.
It shuts down while seems to be cycling while driving. In order to have this cool I need to power off the ac switch and back on, for this to correct. I also, notice this has occurred when I give gas to pass another vehicle or just to get up to speed. Its like a vacuum shuts the cooling down of the ac.
Come on Chevrolet, it appears by the results I've looked at on consumer reports complaints like this, it has been awhile. and there are a few stating the same. I like this truck. Just want it fixed before the warranty expires.
Also, have noticed engine hesitates when slowing down to a stop or taking off from a stop, not sure what this is as well.
Currently sitting at dealership in Huntsville (Wiesner Chevrolet, Buick GMC Cadillac)
On a regular, but not consistent basis, the air conditioner compressor does not cycle. It doesn’t matter if inside or outside air is used.
After the cold temperature is reached inside and compressor shuts off, but does not restart automatically thereby blowing hot air. I must turn the AC switch off and then back on manually to get it to operate. There does not seem to be any problem with the compressor.
Dealer states others have this problem but they don't know how to fix it.
I have the same problem as previously reported by another individual. When the fan is turned on the AC comes on. I have also seen the outside air light change. This only happens when the truck has been off for several hours. I do not have the climate control option so it should not be doing this. It has done this from day one that bought it. Dealer reloaded the software but it did not fix it.

A/C turns on when fan turned on or turned up
I can't believe I'm the first person to complain about this. Since truck was new it showed this issue but dealer has not witnessed it on any other vehicle, nor can I show them the problem because it only appears the first time the truck is started after being off for several hours to a day.
When I turn on the fan from off to any setting, or turn it up from any setting, the AC comes on 99% of the time. Doesn't matter what the temperature knob is set to or how cold it is outside (and of course the AC is off to begin with).
Strange thing is that my car model has the lower option package for climate controls, i.e., no AUTO climate feature should exist (I don't have AUTO on any knobs), yet in one of the photos of the display I show clearly that the car is setting itself to AUTO mode sometimes when I start the engine. I can turn AUTO mode off by hitting the vent buttons, but cannot turn AUTO mode back on with any button so that makes me think this is a software bug. However, I don't believe that this AUTO condition is related to the AC problem since I've seen AC come on either way.
In short, AC should never come on in the model I have unless I specifically turn it on with the AC button. But it does! So I need to constantly be turning it off whenever I start the car in the morning if I turn on/up the fan.
I would love to hear from others who have this issue. I lodged a concern about it using the GM web site support chat, and as far as I can tell there is no acknowledgement of it being an issue from their end. I have several videos proving it's real (will try to get those on YouTube eventually and add link to them).
Update from Jan 17, 2016: 3 videos added showing AC turns on with or without AUTO mode being on by default
