More than likely, you have a blend door actuator problem. Locate the faulty actuator under the dash, usually on the firewall, and replace.

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.

Rear heater not working


Possible blend door motor (controls amount of heat that comes out). Or heater core in back is clogged, or air bubble. If your able to locate the two heater hoses that run to the back of the vehicle and check to see if there hot next to the heater core. if both are hot (be careful not to burn yourself) then the flow is good usually. need to pull the panel off and check the blend door motor is working when you turn the rear heater control to cold to hot. let me know what you see

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.
