windshield wiper motor

[Jerome]

Okay I got the new one on the 30th and did not have time to put it in, this morning I woke to6 inches of snow so I went out to fire up the tractor and low and behold the rear wiper is now working. I had just put it back in temporally to keep the wiring from shorting. go figure.

Funny how that works... The old motor must not be ready to be replaced yet.

I had one that acted that way. Worked when warm but refused to move when cold.
Took it apart and discovered that the connections from windings to the commutator were bad.
The factory crimps them rather than solder, so I carefully cleaned the laquer off of the wire ends and soldered wherever there was a crimp.
Saved the wiper!

My take is that the ambient cold would shrink the crimp joint and make for 'no contact'.
That plus they counted on crimping to cut thru the laquer insulation coating.

I was wondering how to remove the wiper motor on the front window of a John Deere 5510N.
