92 300e How do I loosen the interior leather / plastic to get behind to tighten fasteners on the wood trim. Its just loose enough to make a vibrating noise when driving over rough road.

You're going to want to remove the whole door panel. Search the forum for instructions. You can make sure everything is in check back there and tighten down your wood. It'll take awhile to get off/on the first time. After that, you're a pro at it. Best of luck.
