This winter was brutal on my car. During that time I noticed a noise sounding like a metal spoon scraping against a metal bowl, only way I know to describe it. It went away as the weather got better. The other day I tried the ac, which was fine a week ago, and not really cooling off. I turned it off and that sound came back. It happened once in awhile without trying the ac. Always wondered what it was and now I know it's related to the ac. When I turn the ac on it sounds like something catches and then noise goes away.
My question is, could this just be the belt or more? Also which belt? 2001 grand prix gt. Is it the serpentine or something else. Is this a complicated fix?
