I've had this rattle for a while now, but it's increasingly getting worse. It's coming from the passenger side, front area. I've tried buckling all the seatbelts, but it's not that. I've tried whacking stuff (clearly the most efficient method

) and when I do so, the glovebox will rattle, as will the passenger seat. I'm thinking it's the passenger seat. Anyone want to whack their passenger seat and see if it rattles? haha I just hit it dead center.
Anyone else experiencing the same thing? I saw the post about bringing a car to the dealer for rattles, so I'm really hesitant to do that. Any screws that you think I should try tightening?
