it depends on the car, but its usually a bad connection in the wires
It doesn't the motor does
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.
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.
No
It sounds like the fan-belt is slipping.
Blower fan resistor controls electric current to the fan motor to maintain different speeds.
factory recommendation is to cut a hole in the inner fender well to access/replace it.
on a 2003 Honda si the fan motor blows shen removed from car. there is 12 volts to fan . fan will not run when plugged into car. does fan sw have anything to do with this
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.
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.
get in the car when it is cold, turn on the ac, then check under the hood. the fan that is not spinning when the car is cold is the cooling fan
The fan blade would be connected to it.
