Wiper motor question
Ok guys n gals, I'm working on getting my wipers up and going. I got a 91 jeep comanche motor and a universal wiper switch from speedway Universal Windshield Wiper Single Motor Switch. I'm trying to figure out which wires to hook up, on the comanche wiper motor has red, brown, blue, green and black wires. The motor has 5 wires but the switch only has 4 terminals for low, high, park and battery. I'm sure the 5th wire would be for intermitant but I dont need that and right now I have them hooked up to a toggle switch just to use them but would really like to get the switch in. I've looked all over for a diagram for the jeep wiper motor but haven't found anything.

I can't help you with the wiper motor but if you have the switch that is shown in the Speedway link then one of your wires should be for the washer. All the wiper motors that I have used have had an internal "park" mechanism...when the motor sensed that there was no longer power applied then it completed it's cycle and stopped on it's own. With so many leads on the Jeep motor I think that you will need a Jeep manual to decypher it, I would imagine that Jeep had another control unit in this curcuit. You should be able to hook up power and gound to the motor and then the high and low from the switch to make the system work for you. I had a Jeep manual for a 94 but I let it go with the Jeep when I sold it...

Check this weblink out:

I went through the same thing several years ago and was encouraged to purchase a a Cole Hersee 75228-04 wiper switch ($16) from Redden Marine, which with minimal modification fits into the stock location.
The Cole Hersee wiper switch has five terminals. They are labeled: 1) L, 2) H, 3) P, 4) B1 and 5) B2 (B1&2 are linked terminals). The Jeep Cherokee wiper motor has five wires. They are: 1) black, 2) blue, 3) white, 4) red, and 5) grey.
To wire the switch, the following wires should be connected:
Black to Ground source
Blue to P
White to L
Red to H
Grey not used
EZ wiper wire from harness goes to B1
With a little filing of the shaft on the Cole Hersee wiper switch, the original Ford **** can be used giving the stock appearance.
I hope this helps.

Yes, try and find a 91 JEEP wiring diagram for the wiring flow.

I did the same as Lance Hogan with the same Cole Hersey switch bought from Redden Marine. I used a wiper motor out of a 2002 Saturn which I found surplus on the web for ~$15. The schematic of how it is wired is in my Gallery. If you need a clearer version of the schematic I can e-mail you a PDF with better resolution.

There are at least half a dozen different wiring schemes for wiper motors across the different makes. The park circuits, dynamic braking, and motor windings for multiple speeds vary considerably from one to the next. It's possible that you can make your switch and motor work together, but I have my doubts. It's usually necessary to use a matched motor and switch.
