2004 Expy: I have a rattle in my passenger side pilar where the seatbelt goes in for the front passanger. If I pull out the seatbelt, it apprears to go away, but when no one is in that seat, it rattles (maybe the inertia lock for the seatbelt)? Before I take it in and let the service guys butcher the side panel, any one else with this problem??? Anyone know how to remove this pilar panel so I can take a look??
