Windshield wipers not working

I have a 94 YJ and the windshield wipers stopped working. They came on for a sec then stopped. I'm new to Jeeps, I have no clue on how to fix it. I changed the fuse, but still not working. Thought it could be the switch, but the washer fluid still sprays. What could be the problem? Thanks for the help

Mine did that once. Look under the dash near the stearing colum & there is a wire harnes that comes disconected just enough to lose contact. Thats what mine was. I hope this helps.

That, or if you have delay wipers the module could be broken. You can remove it and connect the two harnesses together until you can get a spare out of a junkyard.

I removed my module and connected the two harnesses together.

the good - the wipers worked.

the bad - my column started smoking after about 20 seconds where the switch is located.

anybody have any ideas?

hopefully, maybe the switch is just hooped - will a switch change fix the problem? or....

maybe the motor is old and becoming inefficient? drawing too many amps and melting my switch out?

does the intermittent module have some sort of resistor that limits the amount of electricity going up to the switch?

I dont want to hook up my new wiper swich in case it starts melting the new one


how should I go about this?

You get to put the windshield down.

Once you do, the windshield wiper motor is right there out in the open on the driver's side. You can get an inline fuse, some wire, and a 2 position toggle switch and rewire the whole thing or start testing the wires going into the motor to fix it back to stock (which I wouldn't know anything about).

edit: you should try regrounding the motor once you take the windshield down.

sounds good! I'll try regrounding it first, but does anybody have a writeup for overhauling the motor?

you're in west virginia? i'm in vancouver bc lol. I'm going to try to see if I have a loose ground first thats making my wires run hot.

bigbass - the plugs? are you talking about the harnesses on both sides of the wiper module?

if you are, really don't need a picture... just look under your dash just to the right of your e-brake release, there should be a metal plate there with a box VELCROED to it. that box is your intermittent wiper module.

unplug both sides of the module and then put the plugs together (without the module in the middle). thats it!

if your wipers work after you've done this (you wont have intermittent at this point) your motors and switches are fine, just replace the module.

just heads up though, when I did this the switch in my column started smoking! if your switch isnt' fried should be ok
