The motor needs to be diagnosed to find the exact problem . If the cost of repairs is more than a replacement, then the motor is deemed bad.
99% of the time, the blower motor relay, or resistor block,will be bad if the fan motor only works on high speed.
Use a test light to see if the motor is getting power. If it is then motor is bad. If it is not getting power "jump" the wires on the switch to see if window will operate, is so switch is bad
unplug motor run fused jumper from batt and touch to two wire plug on motor
prob a bad fuse or switch.
remove switch from where it is mounted using a wire , bridge the connections.if switch is bad, it will work the motor while bridged
If it's bad, the pump motor will not start. It can be checked with a volt meter. You should have either 115 volts or 230 volts in and the same going to the motor.
You have to take the door trim pad off and see if there is voltage at the motor but more than likely, the motor is bad.
If a blower motor resister is bad the fan won't work at all or will only work on certain speeds. And you will see on the resistor a missing link where it burnt out kind of like in a light bulb
Bad blower motor fuse? Bad blower motor resistor pack? Bad blower motor - checck to see if it is getting power--if so bad motor Bad switch?
Bad Motor Scooter was created in 1973.
Bad resistor at the blower motor? Bad blower motor switch?
disconnect the connector and run a wire from the battery to the fan if it runs it is good
