Check your rad and make sure it is full. Wait til truck is cold before removing rad cap.

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.

The drivers side heater control does not work. It blows cold air no matter what position the control is in. What is the problem? The passenger side works fine.


try to pop off the panel to the dash and follow the vent sounds like it has become disconnected somewhere and cold air coming from outside somewhere on firewall also check the heater core see if it is blocked by something like disconnected line
