Ignition Pulse Wiper Module Repair Project

[micifus]

Wipers not working right? Will they only work on high or not return to there orginal postion when you turn them off? Well thanks to jeep946, he informed me it was my Ignition Pulse Wiper Module. This a 30 dollar part but, you might be able to save some cash like I did and fix it your self. Here is what was wrong with mine and what I did to fix it.

The module is located under the drive side kick panel, you will need to remove 2 screws, the two connectors, and then it is just velcroed on. It will look like this.


There is a few plastic clips that can be opened useing a flat head screw driver, try not to break them like I did After you open the box there will be a board in it like this.




There are more plastic clips holding the board in the box and it can be easily removed useing a flat head screw driver. Be careful not to bend the connector pins when you pull it out.



You can see by the red square one of the traces has burned up. Something different might of happened to yours but you should be able to tell be inspection if a component or trace has burned up. I repaired the trace on mine with a pice of striped wire and some solder, not my best soldering job ever but it did the trick.Also be aware that there is a protective coating over all the electronics that you will need to gently scrape it off if you want to do any soldering.



Now just put it all together and reinstall!

The whole job took about 20 minutes and saved me 30 bucks, a wroth while DIY project!

HAHA I played around with it for like 10 minutes and couldnt get it to work. How did you do that? I clicked the insert picture button but it didnt work. Do you need to be a surpporter? Oh and you forgot the bottom one

[jeep946]

good job with the write up, now i have somewhere to send people when they ask.

The fix has been floating around for a while, its kinda amazing nobody wrote it up before I thought about doing it when i made the fix, but i have no digi camera, and im pretty lazy to boot.

Hmm it should be right under the kick panel left of the brake it takes 3 screws to take it off, maybe they tucked it up under some where. Anyone with a 97 zj know where it might be???

You have to remove the kick panel and it might be tucked up higher (mine was). It also might be wrapped in the grey foam with the sticky backing that they used int he factory around alot of the harnesses.

From what I remember from when I was asking about mine, they changed the design in 95 or so. 93-95 are in the kick panel. 96-98 are under the hood somewhere, sorry I dont really know any more, I was focused on what applied to mine.

[Decipticon]

Ok I felt ambitious. But its kinda bad news for you 96+ guys.

Thanks guys I got it fixed. I switched a relay under the hood took the one for the A/C out and put it in the wiper and it works it goes back to the normal position and the delay is back. I will stop at the dealer tomorrow and get a new one.
