The final paragraph is most important. The rest is background, however still important.
I really don't want to pay the dealer or a mechanic just to fix a lighting problem, but I have had no success so far on my own. I posted my problem here:
dash/console lighting problem but nobody seemed to know what was wrong. If you don't plan on clicking the link, here's whats going on: My dash lights stopped working, it's not the fuses, not the bulbs, not the rheostat. In addition to what I've done in that post, today I pulled out the digital multimeter. I couldn't find any broken connections where there shouldn't be any, but it didn't help that I don't really know what all the plugs that I disconnected from the instrument cluster do. If you have any knowledge on that please post. I tried using my friends Chiltons manual for up to 84 models but they are way too different to help.
What I need now is some information on the electrical system on a 95 E300D. I'm pretty sure the interior console/cluster lights are on the same circuit (or something) as the headlight warning buzzer since both do not work. I think the headlight switch opens and closes the connection to the console/cluster lights and also the buzzer. How else would the car tell when the headlights are on? Here is a list of things that may help me: schematic diagram of my models or a similar electrical system, info on what all the plugs do that connect to the cluster, accessing the wires that go from the headlight switch to the dash lights, hints/tips for finding shorts, any known repair manuals for my model. Thanks.
