Correct 2 speed Wiper Motor

I have experienced a non-operating wiper/washer at times, everytime I tried to determine the cause, the wipers would start to work again.....yeah. Finally I took the unit completely off the car, sitting at a table and a 12 volt source, I operated the wipers as in accordance to bench checking process written in the manuals. What I found was....the park unit, has points. These points are the key to everything. Also, on the points, mounted into a very little slot is a piece of plastic that isolated the metal bar that breaks the points. If that falls out, nothing works properly. Mine fell out, I glued it back in place and everything is working just like it is susposed to. Also, there is a grounding wire that gets sandwich between the wire connector and the body of the wiper motor housing. The one mounting screw for the washer has a brass strip under it, make sure it is there and is properly installed. this makes the ground. This needs to be clean and a good positive contact. I would think that unless you have actually Burned the Motor, I would think you can get it to work again by cleaning and checking to make sure all of the little pieces are where they should be in the PARK mechanism.
