It depends on the motor. The fan is driven by an electric motor, and it can use a dc motor (as in a car) or an ac motor (as in a house). They are not interchangeable.


Why would the heating fan not blow would be an electrical problem or mechanical where the motor is broken for it.?

could be alot of issues here. In my car, the fan motor was broken, it is also possible that the sensor that controls your radiator fan is broken, could be an A/C relay that is failing. Lot's of issues, but it is most likely a mechanical failure in the fan. I would recomend getting a multimeter and checking the electrical connections on the fan motor.

You did not mention the kind of car. Check the fuses and relay to be sure you have power. Also you have a blower motor resistor and the fan motor. Grounds are just as important as the power source.


Why does a 1991 Honda civic engine cooling fan stays on?

The cooling fan is operated by an electric motor rather than the revolutions of the car's motor. If your fan is staying on I would investigate the electrical systems leading to the fan, if the key is in the on position it is probably allowing power to pass to the electric motor. Otherwise there may be some short in a switch that is meant to shut it off.
