The wood trim (or plastic parts next to it) on the doors of my 1985 380SE is always crackling and making snapping noises, especially the rear doors. We have a lot of bad streets where I live, which seems to aggravate the problem. I don't think the trim is loose, just making noise from rubbing against the adjoining plastic and leather, maybe. I've seen posts on this before on another forum, but I can't recall where and when. Seems rather common, if I remember, but 15 pages of searching under 'wood trim' here found nothing on this subject. Has anyone had this experience, and does spray polish, lubricant, etc., work? I'd appreciate a theory on what causes the problem and any fixes tried.
