CJ5 wiper motor problem

My wipers have been working intermittent for the last couple months. Not a daily driver so I never really looked into it. Tested power to it, and found that the PO decided to use a wire nut to repair a broken wire. thinking that a proper splice with heat shrink would fix it I was wrong. My question is does the motor ground through the mounting surface? if so, the jeep is almost 100% fiberglass so should I explore other ground options. Also, has anyone ever bench tested these units? How if so?
Thanks, Jim.

Looking at the wiring diagram, the wiper motor is supposed to ground through the body.

The wiper motor should have a three wire plug; Green, Black, and Red.

If you hook the Red to 12V and ground the body of the motor, it should spin.
I think hooking the Green wire to 12V would make it run on the low speed, but the motor also has an internal "Park" switch so it may be an intermittent low.

My first guess would be to check and clean all your connections. Also, try hooking up a jumper cable to the body of the motor and grounding it. It may be the ground that's causing the problem.

It was actually half assed by the PO, it only has one of the three wires hooked up to an automotive push-pull switch; the red wire. I will attempt to try the jump cable to at least get it working, do you have a pic of what the wiper switch should look like if I were to try to get it back to stock, with the high and low speeds?
Thanks in advance

The red wire is high speed. Green is low speed. The black should always have power as it puts it in the park position when there is no power to either of the green or red wires. I'll check around. I made up a picture of the switch and where each wire connects to it.

The wiper switch itself has 5 connections. Three for the motor, one hot wire, and one wire to operate the washer fluid pump.

Mine is hacked up as well. I hope to fix that problem over the winter!

OK so the mobile site still sucks and won't let me upload the pictures because they are too big. So instead here is a link to them on my site.

And if you just want to throw in a 2 pole toggle switch to use the wiper to its full high/low/park.
