Just try reconnecting the battery. There's something goofy that happens when you mess with the battery but, by disconnecting it and re-connecting it, the problem seems to go away. I have seen some comments about unplugging the A/C Fuse and plugging it back in, to reset the system. The comments and suggestions have been all over the board...my favorite was, 'I'm switching to Ford!' He thinks he has problems now...Heh!
Hope that helps! It worked for me but, not for others. But, it's all I got.

I had the same problem after a dead battery.
For a few owners, disconnecting battery for 30 min. reconnect resolved the issue. The majority of us, it doesn't.
Further discussion with a GM mechanic, climate control system needs to be reprogrammed. Read back a few posts you'll see what worked for many of us that I posted.
Disconnecting the battery, computer climate control still keeps memory.
If you have power seats memory button for driver 1 & 2, you'll find seat memory is not lost when battery disconnected, same issue with climate control.
This should be a recall issue.

Air Conditioner suddenly switches to heat. Turn car off and turn back on and it fixes it. What is the problem?

Your situation might have a bad electronic door in vent. I forget what the name of the part is....From what I';ve read from others in here it is a very expensive fix. $1000-$1400.
Entire dash needs to be removed.
I'd sell the rig...

ok, I'm going to start this again. the blower still works,but the vent selection knob will not change where the air flows and the a/c snowflake light button does not turn on the a/c.when you hit the button to turn on a/c it feels like the vent just pulling in outside air.The recycle but also does not come on to recycle the cabin air.I have checked all fuses ,they are all good.all levels of the blower switch works,just not the position select switch or the buttons.please help!

Yes my issue was resolved. I posted step by step a few postings back...
It worked for me and several others, simply disconnecting battery for 30 minutes did for others.
If your issue started after a dead battery, you need to re-calibate climate control systems memory.
If issue just happen suddenly without battery problems, it more than likely the electronic door inside vent needs replaced. $$$$$
I forget what that part is called.
