How do you replace the blower motor on a 1994 chevy lumina euro?
AnswerIf none of the speeds work check fuses and the power at the blower motor. Since blower motors work most of the time, the blower motors do burn out. If it works on high speed only, then the blower resistor behind the glove box is possibly bad. MarkCheck the ground to the motor. Best thing to do is ground the motor and see if it works. I have seen this problem before and putting a different ground on it fixed it.
it on the blower motor housing
there is a short in the wire connecting the blower motor or it could be your voltage regulator sending not a constant current to the blower.
I own a 1994 Isuzu Trooper, the blower moter is located inside the truck under the glove box.
I would like to change the blower motor in my 1994 Ford Tempo by myself. Do you have any instructions for me to follow?
hhhhhh
You either have a blown fuse, defective blower motor, defective blower motor switch, or a defective blower motor resistor pack.
