Center console lights ALL dead on 1988 300CE
I'm posting this question for one of my neighbors who has a 1988 300CE (I think it's an 88, it's a W124 body, real nice car). The lights on his center console all died at the same time. This includes, the window switch lights, climate control lights, lighting for the stereo, lighting for the sunroof (and the rest of that upper panel). Anyone have any ideas as to why these would all die at the same time? Is this somewhat common? We've determined that it isn't a fuse, but we're not sure what else it could be. Thanks so much for the help.
