What is another name for the heater control valve?
The heater control valve (sometimes called the hot water valve) is used to control the rate at which coolant flows through the heater core. The valve is located on the heater inlet hose. Manually operated systems may use a cable, a vacuum motor or an electric solenoid to operate the valve.
What happens when a heater control valve fails?
Your car’s heater won’t turn on.
A broken heater control valve may be more obvious in the winter, because it will often prevent the heater from coming on inside your car. If your car refuses to get warm, schedule repair services right away so you can stay safe and comfortable in colder weather.
Why is my van heater blowing cold air?
When the thermostat can’t signal that the engine is warm, the coolant won’t be sent over to provide heat to the heater core and the air will blow cold. Solution: You need to install a new thermostat to get your heater working again. It’s a relatively quick and easy fix.
