Wiper Motor HELP PLEASE

[tonkatrucksryan]

Well I have been replacing the dash. I replaced the wiper motor switch and the wiper motor and nothing works. Im at a loss. I hope someone can give me some pointers. Thank you so much.

You need to start trouble shooting the wiring. The wiper motor system is very basic as there are only three connections. You can find a wiring diagram here -->> 1974-1975 CJ5 Wiring Diagram - Jeep-CJ Documents and Manuals

Start with the fuse, I know it sounds silly. It's a simple system

Thanks I already checked the fuse. All good. Still banging my head against the walls

My Cj also has a painless wiring harness that the op put in. Because of the glass tub I think there might be a grounding problem. Everything else works.

this is a very real possibility, as I recall the WW grounds through the motor housing. try running a wire from battery neg. to the WW motor mounting bolt.

You should be able to diagnose your problem in minutes with a meter and the diagram I linked to.

Do you have a meter and know how to use it?

 

[tonkatrucksryan]

I have a meter but it has been a long time since I used it. Not sure what setting to put it on. I did take a test light to it and there is power leaving the switch. ugh Hope your feeling better CJ

I just googled "how to use a volt meter" and there are about 5 ka-zillion you tube videos on the subject.

Thank you IOport51 I ran a wire last night to the housing and you were def right. I crapped my pants when it worked . I will hard wire everything tonight. Thank you.
