Tonight leaving work. I started my car. It started and all that I could hear is the fan hitting something(like putting a playing card in the fan) from the vents above the CD Player. As I turned up the speed the noise got louder. I had no heat or defrost for 20 minutes. Once that car warmed up it was fine. But I shouldn't have to drive to warm the car up so I can use heat or defrost. It's going into the dealership on Monday. Has anyone else had this problem?
