‘00 Chevy Cavalier, Shorting Fan Motor

Q: I own a ‘00 Chevy Cavalier which I purchased new. Two years ago the engine light came on and the tracking light. Dealer repaired it under warranty. They said it was a fan motor shorting, taking out 30 amp fuse. It worked fine for a few months until the warranty was up, it blew the fuse again. They said it was the fan motor again. They wanted $500 to replace it. I said no because it did not look like the first one was replaced. I refused it, ran another couple of months and the same thing. I have tried leaving the heater mode switch in all positions, but it still blows fuses intermittently. I know the fan does not run until the engine warms up or on defrost mode. The fuse usually blows after the car is left for a few days on start up of the engine. After I refused it, I started the engine a couple times. The micro resets works fine for awhile. Is there a cap in that circuit that could be going dead after being laid up for few days? This car only has 37k on it. Do you think I should change the fan motor?

- Don

A: I have to say your situation is confusing. The replacement fan motor, if replaced and only being a couple of months old, is still under warranty for that part. In addition, the fan motor does not cost $500 to replace. Even if you replaced the fan motor two times you still would not spend $500 in parts and labor! It just doesn’t sound right. I would suggest having your problem diagnosed by another dealership or repair facility. There is either a serious miscommunication problem or you’re being seriously ripped off!
