OK, I have looked at the schematic for 2 days now and cannot find what I am looking for so I am asking for help here. I had a problem awhile ago that I want to get fixed now. Passenger side headlight wiper motor is unplugged. When I connect the connector to the bottom of the light, the washer pump runs for about 3 seconds and then fuse #3 blows in the fuse box. Fuse is a white 8A fuse. I have looked at the schematics that are in the back of the MB Chassis manual and cannot find ANY mention of headlight wiper motors. I see where the headlights are wired and how they go through the # 3 fuse but absolutely no mention of a wiper motor. When the connector is left unplugged, everything works fine, headlights,turn signals, parking lights, wipers, washers,etc.
Can anyone help with this? Is the pass side headlight wiper motor out? Is there a relay that has fried? I don't want to throw parts at it.
Any help/suggestions are appreciated.
