I to am having the same problem but havn't had anything replaced yet, was just getting ready to get under the dash to make sure everything is in order. But I have no idea what the problem could be so if anyone know I too would apreciate the help. Thanks

Welcome to AF. This can be caused by the mode door actuator, or linkage connecting it, not sure but on some GM vehicles the BCM controls this function, but the actuators haver been problematic.

Is this an easy fix, or readaly avalible part?

Yes, but check into the procedure this actuator on some cars is tough to access.

I had the same problem with my 2005 Impala. On the dual climate control there are separate servo motors (GM Calls them actuators) which open up flaps in the air duct to the heater core.

I paid $37.52 for the part at the dealer and it took me about an hour to install.

To access the servo motor, you need to remove the plastic plate below the steering wheel. It is only clipped-in with two clips (no tools needed). You can see the servo motor about 8" above the floor blower vent. It is black and about 3" long and 2" high. Held in with two screws and has a wire harness attached to it (2 wires). Take out the screws, then unclip the wire harness. When you clip the wires into the new one, you can test it easily. If you slide the temp conrol to hot, it spins one way, the to cold it spins the other way. (my failed one only spun one way, and always forced the duct flap to the heat closed).

The hardest part of the job was reaching from below in a tight spot, and getting the screws started after I installed the new one. For the top screw, I laid some duct tape in my socket, and fit the screw head in tight, so I could use the socket as a handle to get the screw staretd.
