Hi there I have that famous warm air driver/cold air passenger problem. I read the previous forums that said to replace the driver side blend door actuator, well I done that and it's still not working. I even pulled the fuse to reset the actuators like it states and still nothing. I'm at a loss of what else could be causing this. Could it possibly be the actual heater/ac control switches could be bad? I forgot to add that this is an 05 trailblazer ext with the slider controls for driver and passenger side heat/cool.
