When I drove my car during my lunch break I turned the fan on because the windshield was fogged from the rain and it made a sound like a piece of paper stuck in the blades. When on high it is much louder and vibrates the interior quite a bit. I haven't had time to check it out further, so I'm asking if it is possible something from the glove box or floorboard could have gotten into the fan/blower or any of the air ducts and caused this?
On a side note (this sounds funny, but...) it smelled a little like cooked turkey after I had the fan on... WTF?
Any ideas
