my 2007 impala blows heat out of the drivers side vent but cold air out of the passenger side vents. The ac button is on and i have the climate control in the cooling positions. I think it might be an actuator if so does any one know how to replace one? please help! Thanks!

It could be caused by a bad controller or actuator. These are just suggestions, it is not a diagnosis. I encourage you to take the vehicle to be inspected by a certified technician. They will be able to offer additional information after a physical inspection.

Please keep us posted.

If you have additional questions, please feel free to contact me.

I have a 04 impala & have the same issue but opposite. I get NO heat from the drivers side whatsoever & have both heat & AC from the passenger side. I am taking it to the dealer for diagnosis but I encourage you to at least call the issue in with your VIN #, this is the only way GM tracks issues for recalls (dealer repairs & customer "complaints"). I am hesitant as everytime I take this car in I get a different diagnosis that prior....how do I know I'm not being bullsh*ted or being taken advantage of being that I am a woman??? I plan to do the repairs myself after getting what I believe to be the problem confirmed by the dealer.
