Is there any help out there (schematic, drawing or picture) for a rear window wiper mechanism that has been forced over center (5 year old pulled down on the wiper arm)? I am having trouble getting it back together.

Another problem is a short or some other problem that is causing my 15 amp fuse to pop after approx 10 min of radio use. I have not yet done extensive troubleshooting. I thought I would check for any history on this subject prior to getting started. Maybe it is not the radioo......? the other accessories on this circuit are antenna, lighter, rear view side mirrors.

Thanks

Your five year-old may have stripped the splines on which the wiper arm is mounted. Start by removing the cap on the end of the arm, then unbolting the arm. Clean out the splines and re-mount the arm.
If the internal mechanism is damaged, then you'll have to remove it from the door panel.

Hi. When this happened on my 1987 760 GLE Estate (wagon) I had to do both remedies, first remove wiper arm, clean out teeth and reassemble. Second remove inside door panel (Haynes manual OK for instructions). Can't remember exactly the procedure but you will see if the internal arms connected to the motor have become dislodged. If so you will have to loosen the necessary bolts/screws and relocate the mechanism, a bit fiddly but not too bad. There was no damage to the motor or attached parts. Make sure you test the swing of the wiper arm before refitting the door panel. Check Haynes if you can. Hope this helps, a couple of hours is well worth it against the garage cost or a new motor.
