For what it's worth, I've had similar problems with TR washer motors: the
motor itself is almost always good, but the little rubber impeller is often
either stripped off the drive key, or is old and hard so the "fingers"
don't flex enough to push the washer fluid out. It would be great if
someone could find a replacement for the impeller.
I can't recall which of the connections was positive. On mine there is a
small label with "+" and "-" near each post.
When I replaced my waher pump, I did prime it by (Ew, Yuck!) taking a
mouthful of clean tap water and blowing it out into the washer intake hose.
If you're not worried about concours competitions, you can get a cheap
(US$5 or so) generic replacement at a discount car parts place (Pep Boys,
Trak Auto, etc) and screw it onto the original mounting bracket.
