89 300se electrical problem
 

I am having a problem with some of the electrical in the rear left of my car. My antenna, rear left window, rear dome light, rear left reading light, and rear left door sensor have stopped working. It will sometimes start working again if I hit a bump while driving it. So my question is: is it just a loose connection somewhere, and if so where? or might it be a bad fuse, and what fuse might it be? Any insight to this would be helpful.

Again my car is a '89 300se w126.

check the fuse box and see if ALL the things glitchy in the lr are on the same fuse. i don't know if they are or not-no wiring diagram to look at. if they are OR if they are next to each other like fuses 11 and 12, as an example, they might share the same power from the ignition switch. i had 1 126 that had 3 things inoperative on a fuse circuit that had 5 or 6 things on it. pulled the fuse box and turned it over, played the wires attached to that fuse. turned out the supply from the fuse to the dead items were bundled into a single terminal, with the live things in a similar bundle that was in better shape. the crimp had come loose and the wires had pulled out enough to loose power, but the black heat shrink made it look intact. if the dead things on your car are fused seperatley, then it's gotta be a harness problem somewhere. good luck, chuck.

Thanks for the reply. Now that leads me to my next question. Where can I find a wiring layout for the fuses? the one thats supposed to be in the fuse box is missing? any one have a nice picture or a link? I have tried searching but have come up inconclusive about it.
