Thanks, I’ll give it a check in the morning!

I was cruising through the forums and found this about the wiper motor:

Quote:

the wiper motors on these are grounded through the bolts and it is very common for them to just all of a sudden quit working. it would be best to try running a jumper wire from a good ground connection to the wiper motor body. i think i have seen some people bolt a ground wire to one of the wiper motor bolts and run it to the body somewhere close by

Grounded through the bolts that hold the wiper motor onto the mounting bracket!? I feel like I’m losing my mind

Gotta ground somewhere.

But, if you were testing voltage to a known good ground, and weren't getting much, don't worry about the ground side of things just yet.

Alright, I solved the voltage issue and I’m getting proper volts. I got everything mounted up and STILL didn’t work. Took it off and I grounded it from the screw to the negative battery terminal and it works fine.

I bought a length of wire, some ring terminals, and fashioned up a proper ground wire. I connected it to the screw holding the windshield washer fluid outlet (name?) in place. It works!

Anyone see a problem with that? Thanks for the input.
