I have electric wipers factory installed.  Intermittent never worked on driver's side and actually blew a fuse when used.  Problem seems to be in motor so I got a used motor off a crashed bus.

The stupid part comes in that the used motor didn't work when plugged in.  Plug badly corroded so I decided to swap the cover plate with cord and plug from the original motor.  Well, used motor still doesn't work with other cover plate from original motor.  So, I put the cover plate plate back on original motor.  Argh, now original motor doesn't work at any speed either!  This was probably a stupid move to swap the cover from a working motor.

Any ideas how to get a wiper motor working after removing and reattaching the cover plate?  Could I have screwed up the little wipers inside that make electrical contact?  I'll have to break down and spend the $150 for a new motor if I can't get this one working.

 Brian, Scott Crosby on the other board is changing his air wipers over to electric and got a good price on them,....if you have to buy one maybe he can tell you where you can get a better price.

From a quick Google search, $150 isn't a bad price for a 24 volt wiper motor.  It probably isn't worth spending a bunch of time trying to find a generic one with the right shaft and spline size.

I would prefer getting one of my current wiper motors repaired if I can.

If you can't fix it yourself, how about an electric motor shop?

Brian : back to basic--do you have power to brushes?    Check to make sure your arm is clear when in place(bearings holding centered)  Ck for broken wires/solder joints.  These are cks  you can do yourself. Shine contact area of brush up with fine emery/sandpaper. clean oil/grease off with elect contact cleaner/carb-brake cleaner will work.  dab of grease on bearings when you reassemble.    good luck.   Bob

Stupid in so many ways, but fixed now:

Original wiper motor worked just fine today, but I swear it didn't work at all the other day.  I tried intermittent and it worked fine until the fuse popped after about five minutes in the middle of a stroke.  I tried the replacement motor and realized the reason the replacement motor didn't work before is it grounds through the case.  Intermittent still blew a fuse as soon as I turned the ignition on.  I then unplugged the motor altogether and the fuse still blew.  It was coincidence before that the fuse quit blowing when I unplugged the motor.  (I have lots of 10 amp fuses!)

I decided to unplug one of the relays for the wipers on the electrical panel and the fuse quit blowing.  I put in a spare relay and everything works fine now.  The relay is shorted internally as some testing shows.  It seems like occasionally the relay would start working and then quit again.  I guess I now have a fully working spare wiper motor if I ever need one.

It turns out the issue was never with the motor, but I considered some places that can repair wiper motors before I found the real issue.  I wasn't sure it would be economical to repair the motor.  Most wiper motor repair places specialized in obsolete motors and I can still get a new one.  I have had a treadmill motor repaired at a motor shop once.
