okay, so today out of the blue, whenever i depress the brake pedal, the rear wiper just comes on. it will even wipe intermittantly if i am at a stop light and keep my foot on the brake. otherwise, while i'm driving, it behaves normally.
the switch is turned off.
so, before i tear into it tomorrow, i wanted to know if anyone has seen this one, or have any constructive ideas about where to begin...under dash, etc.
Have you had the kick panel or sill plates off lately? Run any wires? May have pinched the wiring when putting it back together. I work on cars every day i figure stuff like this out all the time but this is a new one for me lol.
Yea thats why i said check the wiring between the jeep and the hatch focus on the wiring in the rubber boot. Id be willing to put $ of the fact thats where your problem is. Kinda funny actually lol Here's a thought, turn your rear wiper on and see if your break lights come on.
I am betting the issue is that the wire that feeds the high mounted center stoplight is cross-feeding to the power wire to the wiper motor. Of course, for that to happen, both wires must be broken, or at least have the insulation off of them where they are adjacent to each other in the wiring harness. The area where the harness passes through the hatch hinge line is the likely area for this issue.
I don't own an XJ any longer, but I still think they are the best of all the Jeep products ever made. My XJ was my favorite vehicle in my 50+ years of driving.
So...I stick around and give advice.
i had something kinda similar happen to me... everytime i hit the brakes the entire dash would short out, speedo, tach, radio, everything. It ended up being a wire in the rear of the jeep almost in between the speakers in the headliner. just an idea.
I have a 97 xj with the exact same problem. So I took out the fuse (number 22) for the rear wiper and now the wiper stays put but every time I put on the brakes the rear washer fluid pumps out. You go through a jug in a day. Too bad the original author of this post did not circle back and post the verdict. I will check the wires for insulation at the tailgate.
