Went for a little drive about Sunday....and kept hearing a little noise not present before.....couldn't identify it.....something small rattling off & on.... Wasn't any of the places I checked.....until FINALLY.....my passenger moved her feet and we found couple of metal items on the floor.....voila, no more noise!!!
I've had stuff in the door side panels make noise before. Once it was stuff in a box behind the driver seat.
Good luck in finding yours.
