Since the day I bought my car I've had this annoying rattle that appeared to be in the dash. It sounded like a golf ball bouncing in there. I never had it fixed because I did'nt want the dealer pulling the dash. Today with the help of the mechanic we found the rattle was actually the visors flapping against the window frame when we hit a bump. He put stoppers where the visor meets the frame and the rattle dissapeared.
