The Chrysler Concorde does not have a heater control valve. The temp is regulated with a blend air door inside the dash.

The temperature valve actuator is located on the front of the heater case
I do not have heat in the car and the blend door clicks. How do I access the blend door in a 2005 Ford Explorer?
How do i replace blend door motor
Where is the blend door actuator located on a 2005 malibu
The size of the door speakers are 5.25. I have just moments ago replaced mine. This is the dimension of the Concorde is the infinity system.
Cannot speak specifically to a Oldsmobile but, on a Dodge product of same vintage it would be low freon. Either that, or it could be a bad control head, or a bad blend door actuator.
To replace a blend door on a 1999 Voyager, you will begin by checking which side of the vehicle is not receiving heat. Then, remove the glove box door by squeezing the inside of the door toward the center of the door to access the blend door.
need to replace heater control valve on Chrysler Concorde 2000 lxi. heart will not blow hot air. A Concorde does not have a heater control valve. The temperature is controlled with a blend air door. The first thing to check in a no heat situation is the coolant level. Next make sure the engine is reaching normal temp(at least 190deg F). Third you make sure both heater hoses are hot. If one is hot and the other cold the core is plugged. Then you will need someone with a scan tool to diagnose the blend door.
Low coolant? Thermostat not closing completely allowing engine temperature to rise? Plugged heater core? Temperature blend door malfunction in the HVAC housing.
