96 Buick Park Avenue HVAC blows warm on driver's side, cold on passenger's side
I have a 1996 Buick Park Avenue with Automatic Temperature Control. When the heat is up to full (90 degrees), the air from the driver's vents is warm. The passenger air is cold. With a Tech2 I pulled the ATC DTCs. 0041-Air Mix Door 2 Circuit was displayed. Anybody see this before? Any suggestions will be greatly appreciated!
Thanks!

i would guess you have the actuator for the temp door stuck and not working i would go to the actuator try taping on it while switching temps and see if it will move at all
otherwise u will have to check ur voltages to it see if it getting the signal from the control head if it is remove the actuator make sure the door moves free

I second that. We have replace a ton of these actuators for this exact concern. Give it a tap. If she moves, replace the acuator. It is on the pass side toward the bottom of the glove box. You need to open the glove box fully, by pulling back on the rubber stoppers on the sides.
