Wiring Tech: GM column ('89) to YJ wiper motor???

[mbryson]

Wow, what a pain in the arse. Wiper motor works fine when I just use a ground/hot deal. It seems that the GM switch is pretty funky (according to my test light). I don't get any current unless I have the alligator clip on a power source and it grounds to various wires as you roll through the switch settings.

Anyone ever dealt with this? What's the solution? Switch on the dash and screw the column deal? (I'd like to use the column) Isn't the stock YJ column a GM column and basically the same?

i only have experience with 87-91 xj's and 95 yj's and they are gm columns.

Jeep columns pre-80 were basically GM columns. Don't know about after the Mopar buyout.

Sounds like you can just hook the motor up to the fuse panel and then ground it through the switch.

here's a couple of diagrams I have

I stole these from Autozone's website. Seem pretty accurate in regards to the windshield wiper wiring.
