What does the heater control valve do on a car?
Some vehicles (mostly older models) have a heater control valve. As its name implies, the heater control valve controls the flow of coolant through the heater core. To have a better understanding of the heater control valve, it’s important to first know how your car’s heater works.

A pair of hoses connect the heater core to the cooling system. When the driver turns on the climate control system’s fan, a blower motor forces air across the heater core, transferring heat into the cabin. When the vehicle is running, the engine-driven water pump moves coolant through the engine and toward the thermostat.
Is the heater control valve normally open or closed?
Depending on the system design, the heater control valve may be normally closed (blocking coolant flow until activated) or normally open (allowing coolant flow until activated). Some heater control valves are operated via a cable or engine vacuum, while others are electronically controlled.
