I have cool air coming out of the vents on the driver side, and hot air on the passenger side. My car has dual climate control. Are there 2 separate heater cores, or is it just one? What is the layout of the heater core with dual climate control? Anyone have this problem? What could it be, and how do you fix it?

 

Anyone?....Buehler....Buehler....Anyone?

 

There is only one heater core. There are 2 temp actuators one for the driver and one for everyone else. Codes?,ACM, drivers side actuator could be cause.

 

Thank you, that is helpful. Where is the driver's side temp. actuator located? Behind the dash, or in the driver's side door?

I don't have a diagnostic machine, and it is not possible to pull codes from my onboard computer.
