1999 buick century climate control problem

Hello
I would like to know if anyone else is having trouble with the duel confort climate control. I have heat on the driver side and cold on the passenger side.
I replace the whole climate control unit but found out it did the same thing as the other one. Any help would be appreciated. Thanks

So I guess your complaint is not getting any heat on the passenger side?

The dual climate systems use temperature control actuators to control temperature via a valve in the lower part of the heater/evaporator core assembly. Each side has its own actuator.

thank you for your response can you tell me how to get to this problem,is it under the dash .

For the passenger side you have to remove the glovebox first. Then to the upper left hand side of the opening you will see the temperature actuator. It is triangle shaped and will have an electrical connector. Towards the bottom is a shaft that you will see move as you adjust the passenger side temperature control. Vary from cold to hot. If you see no movement it will either be missing the positioning voltages from the climate control unit or the motor is bad.

thank you bnaylor will try that and see. thanks again
