Have you checked you heater control valve or heater core if working properly.
the heater control valve or DCCV (dual climate control valve) is located next to the radiator on the passanger side just below the high pressure side service connector
check the heater control valve it should be 10 ohms of resistance
How to fix heater in Buick there is cool air ,fan is work .but no warm air
The heater control valve is located on the front part of engine compartment. Its next to the radiator on the passenger side.
Most likely it's the heater control valve. If the heater control valve leaks a little it can allow a small amount of heated engine coolant to circulate through the rear heater core.
Check heatertreater.net for diagnostic information and a fix for the blend door/actuator problems endemic to this model.
The heater control works along with electrical controls to properly operate the heat. If the unit is electronically controlled, then computer codes can be checked to see if there may be a problem.
No. There is no coolant flow valve.
