Nice ! Made me go out and look at the wiper motors I have . Got one old
one that's reversible , but I'm not sure how it's wired , has a good worm
set in it . It has one black going to the field coils , a red and a green ,
one to each of the two brushes . The other is a sealed motor , newer and
only 2 wires - looks to be a PM motor . I can't remember if this is the that
one has a stripped gear on the worm , that might have been the one with the
fried commutator that I tossed .
