Hello, I have a 2001 S 500. I want to buy a part that is missing from my exterior, but I don't know the name of it. It is a small square plug, nearly 2 inches across. I see 2 of them on my passenger side-one underneath the front door panel, another underneath the rear door panel. However, on my driver side I only see one square plug-one underneath the front door panel, but an empty square hole underneath the rear door panel, where I can see a couple of wires through that empty hole. I want to buy the missing piece to cover that hole, does anyone know what these square plugs are called?
