I thought it worked putting in a new relay but the other day it was raining and it started acting up again. They don't return to home position and when you have them on delay the wipers got 3 times across the wind shield before they turn off. I don't know what else to do.

Body Control Module

BCM

Attached to the Junction Block, under the driver's side of the instrument panel.

The BCM utilizes integrated circuitry and information carried on the Programmable Communications Interface (PCI) data bus network along with many hard wired inputs to monitor many sensor and switch inputs throughout the vehicle.The BCM supports many body electrical features such as Interior Lighting, Exterior Lighting, Intermittent Wipers, Remote Radio, Accessory Delay, and Heated Seats.

That seems to be the answere, did look into that?

Well with the BCM im not sure you might just need to replace it. Umm take it out and take some pics, see if you can open it up take some pics of it. Im not sure its a serviceable part. I think they can be rebuilt...

this might be the same on in the jeep I dont know

Thanks, with your directions I fixed the delay module on my 95 GC. It works like a champ again.

In the newer ZJ I believe the problem lies in the Body Control Module (BCM). If you have a way of swaping this out with another BCM I would try this first.

Of course I found this thread after I repaired mine!

The picture of your module with the red square was exactly what mine looked like.
Wipers would work on high and low but would not park or work on intermittent.

I soldered a piece of thin gauge buss wire from terminal to terminal to bypass that section.

For anyone reading this writeup - Just don't make the same mistake I made when testing it.

I decided to install and test the bare board before I put the box back together.
Good idea except it was dark out and I installed using a flashlight.

I didn't notice that the inside of the connectors were not divided between the slots so two of the long flat board pins contacted each other inside the connector.

It popped the buss wire right off it when I turned the ignition on.
After the re-repair and installation with the housing I had park but never got intermittent out of it again. Not sure if I zorched the component that controls the timing or if it was already shot before I messed up.

So put it back in the housing before you test it.

Happiness is clear in the cab and 150 over 150.

The reason the traces burn up is due to a surge in current typically cause by something inhibiting your wipers from moving. I burn the module out twice in one week during the winter by using my wipers with a lot of snow on the windshield. the snow prevented the wipers from moving and cooked the module, Check you linkage and wipers make sure there is not hindering the movement of the wipers.

My next project is to make a fuse to protect this module
