Good day together, my name is Karl-Heinz and I own a 280 SL R129 BJ 1997. Last week when I parked my car and closed the cover everything was fine, after about 3 hours I wanted to open the cover but it only clicks behind the cover box and the switch lamp lights constantly as soon as I turn on the ignition, sometimes the windows drive and sometimes not. what possibility is there or does someone know a capable mechanic in the greater Duisburg area?
