Just wondering if special tools are required to remove the inner door panel on a 1994 E420. I don't see any screws to speak of, so I assume that it is held on with pressure clips of some sort. I have a buzzing noise coming from the panel, the kind that goes away when you press your arm up against the panel, that I would like to eliminate. I assume that if I take the panel off and drive, and the buzzing is eliminated, the problem must be within the panel itself.
Thanks in advance for any help.
