My brother died last year and we inherited his '92 Mercedes. She needed a little work (mostly buffing and waxing), but she's an awesome car. Our number one problem seems to be that we can't get any instrument panel lights to come on. There is not a single light coming on either, not even in the center console and we checked all of the fuses and the all seem to be just fine. Does anyone have any ideas what may be causing the problem?
