My gmc yukon 2000 slt rear ac blows hot air when i have ac . on and the front works fine .


I have a 2000 GMC Savana Van SLT with front and rear AC/Heat. My front would blow hot while the rear blew cold with AC on. It turned out to be low on Freon. It's hard to know if you have the right amount of freon installed because pressures vary depending on the ambient temperatures. So the best way is to remove all the freon then reinstall the recommended amount as listed on the evaporator housing near the firewall. This worked fine for me... works like new after installing the correct amount of freon.

To check the rear expansion valve, see if the a/c lines are different temperatures. One line to the rear evaporator should be hot and the other cold if it is working.
Try to recailbrate the blend door actuator. Remove the HVAC module fuse. Wait at least 15 seconds. Replace it, turn the key on and wait 40 seconds

How can I determine if my compressor is out on my


If you still get cold air out of the rear vents but the front only blows hot air you may have a bad temp door actuator in the dash, it may be stuck on hot and not able to move to cold air. However if you are low on freon with a truck that has front and rear ac then there will be a temp diff between the two. If it is hot air out the front like the heat is on then you have that actuator problem but if it is cool air about the same as the outside air temp then you may be low on freon.
