Ir is either a defective fan motor, blown fuse, or defective thermal relay.
defective motor will not run, also cause the blower motor speed resistor to burn out and eventually blow the fuse. a motor with defective bearings will draw excessive current causing either the fuse to blow or cause the motor to overheat
Gas, and What Wiki User said "a motor"
Blower motor resistor defective
Check for a blown fuse. If the fuse is good then apply 12 volts directly to the blower motor. If it runs then the Blower Motor Resistor Pack is defective. If it does not run the motor itself is defective.
Defective Blower Motor Resistor Pack.
Pull the fuse, or disconnect power at the motor, until you repair the problem. Sounds like the blower motor switch is defective.
Yes - you can run a 1200 watt motor on a car battery - until the energy of the battery is exhausted.
Try cleaning or replacing the iac motor/valve, as a guess.
I turned on the motor to run my car.
Check to see if it is getting power - if so defective motor Run a "Hot" line to motor to see if it starts Check fuses Check sensor at rear of radiator
Check the run capacitor, if defective, can cause the fan motor to run hot and stops till cools off, on n off. And the sound is a little different while running, it is hard on the motor.
