    the temperature motor which works the doors in the hvac plenum is probably defective.find a manual that will tell you where it is.under the dash.not sure if left or right side.some times if you tap it it will start working.if it does.replace it.not sure if part stores have it.you might have to go to dealer.should not be to expensive.

The A/C unit is not blowing cold air in the front. The back is blowing cold and we have re-filled the unit. Still is blowing HOT air?


your split manifold located on the firewall that sends and directs the refrigerant from the front and rear depending on your setting on the dash is plugged or the climate control on the dash is not responding and there could be a fuse,relay,broken wire,but there cant be a leak or either side wouldn't cool

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.
