2009 chevy AVEO 5 ac blows hot air


The guage needs to read between 35/40 psi.. If its much higher you may be overfull, this causes it to not cool.. Fix by letting some freon out, then top it back to needed pressure.. If pressure is correct, it would be a clog in the system.. Usually an orafice tube or accumulator..good luck!

1997 chevy silverado blows hot air only through vents


If you know for a fact the compressor is running and one of the lines is cold, I would look for a blend door problem. The blend doors direct air thru the heater and evaporator.

Had exact same problem with my 2006 Chevy Silverado 1500. Would blow hot air thru drivers vents only and sometimes if I turned truck off and restarted would blow air conditioner for a bit. Rec'd recall letter from Chevrolet in January for this problem.

The ac is blowing hot air the freon charge is good but the ac still blows hot air whats the problem with my 2000 chevy silverado?


Is the compressor kicking on? If not and the pressure is in the normal range then I would say that the low pressure switch is stuck. It is located on the canister right beside of where you hook up the freon. Unplug it and cross out the plug and see if it starts then.

2005 chevy 2500hd duramax driver side vents blow hot air


It sounds like the HVAC head needs to be recalibrated, most likely when you unhooked the battteries you lost the memory to the control head, it's in a default position/state.

One side air blows cold one side blows hot


GM has a known problem with the electric actuators that operate the blend and temperature doors in the HVAC system. There are 4 or 5 of these in the typical system. Any can start sticking or binding and cause this problem. Sometimes they can be cleaned, or they might need to be replaced. Sometimes resetting the HVAC system controller by disconnecting the battery for 10 minutes, then reconnecting it, will correct the problem.

1994 Chevy Silverado temperature guage shows hot


Flushing the radiator, replacing the radiator cap, adding new coolant, replacing the sensors and a new thermostat solved the problem. Probably didn't need to do all of these things - but since we just purchased the truck, and given the fact that is probably hadn't been done in a while, we chose to do all of these things (which really didn't cost a whole lot), it's running like a charm now.
