Heater fan and cooling fan.
If it is the heater fan, there is a short in the wiring. If you mean the cooling fan on the radiator, it is normal with some vehicles.
No. The heater 'fan', more commonly known as the blower motor, is the one inside the vehicle cabin that pushes warm or cold air for the cabin heat or air conditioning. The cooling fan is the engine cooling fan under the hood.
The fan has two different ways to turn on in the Escort. Check the temperature gauge and its circuit as these control the fan when the engine heats up.
No, that is just for cooling. The heat from inside is transferred to the outside unit and removed by the fan.
Why does your ac and heater fan turn off and on
HVAC fan? Engine cooling fan?
Sounds like you may need a resistor.
I believe it turns on and off the fan (1 out of 2) that cools the engine according to the temperature it's at. If it doesn't work the engine may not know to turn the fan on and the engine could overheat. Here's a tip. When you turn on your A/C or Heater, both fans come on. The A/C cooling fan and the Engine Cooling fan.
yes
It will take a little longer for the cooling system thermostat to open up if the heater fan is on. The heater fan and heater core act like a small radiator and disperses heat energy when in operation.
If the AC or Defroster is on, many vehicles will also turn on the cooling fan.
