Here are the tips to identify the failing heater control valve in your car.

The heater control valve wears out and develops a crack in due course of time.

This causes the coolant to leak from the valve.

The heater control valve can also leak due to excessive corrosion.

Abnormal heater behavior

If you observe abnormal behavior from the engine, then it is related to the failing heater control valve.

A failing heater control valve will not be able to control the coolant flow.

This causes a problem in the functioning of the heater of your car.

In addition to this, the heater may blow hot air only at certain times but not all the time.

Malfunctioning heater

This a very common sign of a failing heater control valve.

The heater is unable to produce warm air when you require it.
