The heater fan ONLY blows the air, it does not make the temperature of that air. Your heater temperature controls how hot the air is. Adjust your heater temperature for hotter or cooler air.
we changed radaitor & thermastate , now heater blows cold air
Whats the problem? Blows cold air with the heat settings on?
A car heater taps off engine heat. If you aren't driving, then the engine is cold and there's no heat for the car heater to use.
You probably have a bad thermostat.
A heater core in a vehicle takes some of the heat from the coolant and runs it through a heat exchanger. The blower in the car that blows hot air into your car runs through that heat exchanger which heats the air that enters your car.
It's either the thermostat or the heater controls.
heater core
check heater core could be cloggedCheck the engine coolant level also.*no, the heater relies on the engine for heat and when you drive the engine warms generating heat:)*
The heater control valve is bad. Sometimes the dual heater control valve will go and the AC will blow full heat.
