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

That's likely a window motor rather than a wiper motor, Terry. It
should work well!


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 .

Grab the output shaft with a pair of channellocks and energize. You'll
know in a hurry if it's bad. g

No , it's definitely a wiper motor , still had the arms to drive the wipers
and the park switch in the assembly when I got it . I just can't remember
how it was wired , or why I disassembled the motor part . That might have
been because I was trying to figure out the wiring .
Some multi-wire wiper motors are multi-speed, and some GM wipers
reversed to park (hide-away wipers) Have not seen a wound field wiper
motor in several decades. Virtually all have been permag since the
late sixties?? The English stayed with wound field wiper mnotors
longer than just about anyone else -LUCAS
