My 08 Edge is making a rattling noise from the driver side rear door.Sometimes more than other,had the wife drive me around trying to figure it out.Tightened the screws,when i shake the door i dont hear it,hit a bump on the road and there it is.Anyone here have this prob. and how did you fix it?Looks like the prior owner had the rear panel off as i see some pry marks on the lower part.Seen others who state it could be the sunshade,any ideas?
