well if it happens to be your seatbelt recoils... I wish you the best of luck... that being the same problem I have yet to figure out with my trunk... for the life of me I can't figure out what I could do to them to take out the jingle... where do you think your noise if coming from? turn up the bass hop in the back seat and have a good listen.. and if anyone has any suggestions on the seatbelt recoils please fire away...
