Wiper Motor Pulse Board Module
Where is this thing located on a 94 Jeep Cherokee XJ 4x4? I've checked the kick panel on the driver side, not there. Check under the steering column, from what i can tell not there....where else might this be?

I have a 95. It is a black plastic "box", similar in size to a pack of cigarettes, velcro'ed to to lower dash piece. It says "wiper delay" on it.

I finally found the sucker. Literally just reached up under the drivers side lower dash and there it was just like you said, velcro'ed. Easiest thing to remove ever haha. Wish all fixes were that simple! Thanks

What you are probably going to find is a burned trace on the PC board. Open the module up, remove the board and look at the backside where the traces are. If you see one that has burned open, bridge the gap with some solder, or if it's too large a gap, a short chunk of wire soldered in place.
It is also good practice to re-flow the solder on the input and output pins as long as it's out. (heat them up with the iron, add just a touch of new solder so they flow)

Mine didn't have any Burnt out spots on the back. Found one at the local pull-a-part from a 96 and now it works!!

Lucky, I've been through 3-4 of those from Pull A Part and none of them have solved the intermittent issue, I also installed new linkage joints and that part works great now.. Were $5 bucks in the help section.

sorry need to bring this one back from the dead.
After my origonal motor finally gave up I went and dumped the $90 at advance to get a reman one. This one worked fine for about a month then one day it quit. The solenoid on the motor still clicked but the wiper would not move. So I went and swapped it out for a new one and installed it, this one worked for about a day then started acting up. It would work for a little while then quit. then it would go really slow and get stuck randomly. So I went and got that one replaced. I haven't installed the newest one yet because I wanted to look into this pulse board thing. Could these problems be pulse board related? and where is the thing on a 1999 XJ? it isn't in the spot that it is on the pre 1997.

Its possible install the newer motor remove the wiper control module .Take the plugs from it plug them together see if motor works for a while . This will give you just regular wipers just so you no ,there will be no delay setting .

My guess it has it has something to do with the pulse. You may also want to look into possible relay/fuse issue??? Not sure if the 97 have a relay/fuse for the wiper motor but wouldn't hurt to look and possibly replace seeing how it would be an easy cheap fix. Other than that I would try the idea posted above about removing the mod and seeing if that fixes the issue. Best of luck to ya.

The only thing about that is that the 1997 and up dont have a constant wipe setting. Its either intermittent or push and hold to spray and wipe its on a 2 position switch.
