Not sure if it is the same rattle I just had but both doors had it. My problem were little felt strips between the trim panel and the top lip of the door shell it is sitting on. I took some adhesive backed velcro, the soft side, and lined that whole edge with it. Took care of my problem lickiddy split.I have an annoying rattle in the front passenger door when I take the RL over bumpy roads.
Any advice on addressing it?
