So I've been having electrical Issues with my 1993 W250 w/ Cummins, the lighting has been acting up and I know a lot of people have been having the same issue but I'm stumped, I've checked all the fuses and they check out except that there is no hazard fuse. So the front lights/turn signals work perfectly but the rear is where it's all gone bad. So this is what I've found, the left rear side has daytime running lights not the right doesn't, but then when I hit the Left brake doesnt illuminate but the right does as well as the right turn signal the left doesn't and right does! I'm very confused... need help and input from somebody experienced with electrical and/or has fixed their problem... thanks
