So i started my mj yesterday and the wipers are stuck on. How do i just get them to turn off. Isnt there a relay i can just take out? If so where. Its driving me crazy.
I searched the forum first and couldnt find anything that was quite right.

 

Could be the switch, probably just unplug the harness for now.

 

You should see a 5.5 amp circuit breaker, mounted vertically in the far left side of your underdash fuse panel. That's for the front wipers.

 

If its a fuse its not there and never was i beleive. Always worked before.
Edit: im going to try to change the switch tomorrow. Update then.

 

I'm not sure if your MJ has it but my '89 XJ has a wiper control module that's velcro'd under the driver's side knee bolster (near the steering column). Remove that module and it should make them stop.

 

Okay thanks ill try this first. Also everytime my blinkers go down my lights dim and come back (like my truck is blinking lol). Hoping if i can get the darn wipers to stop the lights will too.

 

I'm wondering if you have a short somewhere in the harness under the column. Let us know if you find that control module and if disconnecting it helps.

 

I inplugged it and still didnt work. Any other ideas?

 

Which harness?

 

You unplugged the intermittent wiper module and the wipers still wouldn't shut off? If so that really only leaves a short somewhere in the harness between the module and the wiper motor. Or the big connector @ the firewall. Pulling that module should interrupt the wiper switch. Are you sure you pulled the right module?

If you didn't have intermittent wipers I'd say the always-on +12V to the "park" circuit was finding it's way to the wiper motor (a bad park switch in the wiper motor itself will do that). But pulling the intermittent module (if there is one) would interrupt that too.

 

Im pretty sure it was the right module. Mine was grey right under the steering colum looked like this

 

Im pretty sure the short is between the module and wiper motor. The lights diming when the wipers go down also seems like its a short.
Hope it rains tomorrow if i cant get 'em fixed

 

You could unbolt the arms until you figure this out... but keep'em with you just in case it rains.

 

Yeah thats what i did. Might take this one into a shop and see if they can at leadt tell me whats going on.

 

Update. So my wipers started to work again out of the blue a while ago and kinda just forgot about them. Rightbefore They started working had replaced a couple lights in my dash and somehow the cruise control swithch/button fell of and i just taped the wire ends and left it out. Today i hooked it back up and when its connected the wipers stay on.
Does anyone know if it could be the cruise control or any other ideas.
I dont use cruise control but i like things to work the way they were meant to.
Any thoghts would be great.
