Thanks for the links - they were a HUGE help in getting the motor out.
I took the circuit board off - the solder joints seem fine, but the tip of one of the brushes comming off the board is worn (I guess they are brushes or contacts). Could this be the culprit?? Can I replace the brushes?? or the whole board???
Inside there is what seems to be a toothed plastic wheel with LOTS of grease on top. From another post I kind of thought this would be dry and in need of grease. Should I try to take the wheel off?? Still can't figure out how this makes the wipers park.
Thanks for all the help I've gotten. I feel I should put a check in the mail......lol.
