Why does my car heater go on and off?
Most Common Causes of Car Heater Malfunction
The heater switching system might be faulty. The cabin air filter might be choked, restricting the airflow through the heater core. The thermostat valve might not be working right. The heater core might be clogged.
Why does my car heater only work when I press the gas?
You may also have a clogged heater core that may be prohibiting the outer linings of the heater core to get hot. As you know, the heater core is a series of tubes that the coolant runs through that generates the heat from the warm coolant after circulating through the motor.
Why does my car's heater blows cold air when stopped?
You may have trapped air in the cooling system or the heater core may be partially plugged up. Engine coolant is delivered to the heater core through two heater hoses.
Why does my car heater only work sometimes?
Dirty or low engine coolant can make it so your car heater works only periodically. If you're experiencing on-again, off-again performance from your heater, this could be a sign you need to have your engine coolant inspected.
