I was driving today, and everything was just fine all day long. I pull into my driveway, and as the car is idling, before I shut it off it make a nasty noise. I think to myself, what the hell is this? I believe it is coming from my fan, so I shut it off and, lo-and-behold, my fam wiggles around loosely. My guess is that isnt normal. Any one know what would cause that? Also, should I replace the fan or put an electric one in? If so, which one should I use?
