I had taken my wiper motor out to work on the seals and lube, and could not get the ground to work any more when re-installed, so it wouldn't park. I did not even disturb the bushings and ground strap, but it seems just taking the motor out and putting it back in was enough to disturb the inferior ground connection made with the rivet. I think it's a good idea to always remove that rivet and replace with a screw or at least always whack the rivet and bench test the motor using that ground connection while the motor is out, it would have saved me a couple hours of trying to figure out what's going on with the parking. I added a ground wire rather than take the motor out again and work on it.
