I just fixed mine . feel the suction [larger] freon line in the rear of the veh. if its not cold your expansion valve is plugged up. if your crafty it can be cleaned and reused using cleaner n air compressor, for best results replace it for bout $25.00

Air Conditioner Problem


the most common problem here is a defective air temperature control blend door actuator, this is what moves the door that controls air flow across the heater core or the ac evaporator core, to replace this requires u remove the dash assembly.

Yukon A/C, rear blows cold, front ducts a LOT warmer.


There is only one A/C system split into 2 zones. Check the blend door actuator, it may have failed in one position or something may be jamming it. Also check the control panel in the dash, My 98 yukon did the same thing, no matter what temp you selected for the front it would blow at about 70 degrees. There is a circuit board in the control panel that gets corroded and one of the circuits controls blend door operations. Have a look.
