My Pontiac Grand Prix is having problems with the inside blower fan. Intermittently when the right front wheel goes over a ridge, bump, or hole, the fan makes a vey loud grating noise. It stops if the fan is turned off. The fan can be turned on and there is no noise until a bump etc. The fan also runs louder when the car turns a corner. The service place says that the blower motor is gone. It seems to me that the fan is hitting something or there is something missing that holds the fan in a stable position. The service place has taken the fan out a couple of times and still they have the same diagnosis. This is a very expensive fix, but its a pain to keep turning the fan off and on - winter is coming. Is there anything else that this could be?

Thanks.

Welcome to the forum, if the bushings /bearings in the motor are shot, the shaft that the squirrell cage mounts to can move. I would have to check the blower motor, if the shaft is loose as far as up and down, side to side. Replace the motor. I looked at an online partsbook, saw one for about 80 bucks, not counting tax. If you do the work yourself, the labor is free.

I just replaced mine today, its an easy fix, tools needed are a 5.5mm socket and some pliers and a flashlight. Under the glove box or under the dash there is a panel with 3 black clips. Pull them out and disconnect the light. Set it aside. The blower motor is right there. 3 screws hold it in. Took me 1/2 hour to fix mine. I also have 120k miles on my gtp. Must be about the life of them. Good old made in korea parts.
