Can someone please tell me what may cause my gauges in my 1989 560SL to
appear to be shorted out. I've checked all fuses and that does not appear
to be the problem. When my gauges stop working, my windows cannot be
operated. However, the gauges do not stay shorted out all the time; they
sometimes work and sometimes don't.
IS THERE A RELAY THAT CONTROLS THE GAUGES?
