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.
