Well, we bridged across a burned out lead on the top of the motor.....and the motor works again.......but now it parks in the middle of the sweep, instead of at the beginning. In other words, the arm, at rest, sticks straight up at 12:00 position.

Distracting, but I'll take it over $150 for a wiper motor.

I suppose it's possible an internal part that regulates the park position burned out......and the thing doesn't appear to want to be opened up, even by somebody rebuilding, if they could be found.

Tell you one thing, that salt and other crap sure ate up the pivot pin. Had to clean it with a wire wheel just to get it semi-smooth again. All greased up now, though, and working great.

TIP: If your rear wiper is slowing down, you'd be well off to go ahead and pull that arm and motor out. The linkage is just held inside the mounting arm wiht a C-pin. Back it out, clean it up and grease it, and stick it back in. Easy work, and well worth it.
