The map light cover can be popped of by gently prying with a amall putty knife or similar tool. The housing comes out by removing 2 screws. After stumping the parts man at the Chrysler dealer for a replacement for one of the bulb sockets I flipped the housing over and noticed it had a Mercedes part number. After a quick search for Mercedes parts I found the bulb socket available for 93 cents. Isuppose you could also go to a Mercedes dealer.
