Passenger side heater doesn't work. I have replaced the air door motor which controls the heat directed to the passenger side but that didn't help. This is controlled by the Climate Control and appears to work properly. Found out that the original motor was still good of course. To go beyond replacing the motor that controls the heat doors requires spending a lot of time and therefore money at a dealer. In cold weather (live in Colorado) this makes it tough on the passenger. Very irritating!
