A/C compressor is engaging but still blowing hot air into the cabin. What can I check

put in full auto make sure the button with snow flake is not pressed this will turn ac off and put in recurcuit mode also.
Had this happen with the snow flake button.

Thanks, I tried that could it be some type of relay because one of the a/c hoses gets cool and starts to sweat but no cold air in the cabin

Mine was blowing hot out of one side and cold out of the other... I took it to the dealer and they found the Control unit was bad

They replaced mine with Part Number: 25938052 Hvac - Controls - Dash control unit Dash control unit, corvette 2005 - 2011

Dealer time IMO to many possibles

I agree, could be many things. If you know it has refrigerant in the system, sounds like it does from your description, then it is "most likely but not positively" the head unit or a mode actuator curtain.

What year is your car?

2006 , This afternoon I was out and the service charging system came across the DIC and shortly after that the a/c started to work. But, after I shut the car off and restarted the a/c was no longer working

SOME ONE PLEASE HELP ME !!!!!!!!!!!!

Its worth a try...Disconnect your battery pull both possitive and negitive off, i beleive its for 30 Min and the computer should reset...

It maybe only 10 Min.... but i would wait the 30 unless someone can confirm the time.

Thanks I will try that after work, and let you know if it worked or not

Are you on the original battery? When the battery is near the end of it's useful life, many weird things can happen.
Strange that you got a "service charging system" message, then the A/C came on.

patiently watching for results. only half of my a/c is currently working.

I did the battery disconnect for 30 min this evening, and the ac diverters work again and it is blowing cold and strong.

It is amazing what disconnecting the battery will do to help with problems. Probably should be one of the first things we try when we are having problems.

That's crazy...only my passenger side air is working right now....

Sounds like it's time to disconnect
