the TSM has several suggestions

couple questions, does it happen on high and low? when the wiper stops straight up how do you get it to go back down? do they go to the park position ok?

does it do it if you remove the arms?

do you have 12.5 volts at the motor with the engine running?

swap out the circuit breaker in the fuse panel

replace the motor

if i push the wipers down to the bottom as soon as you turn the key on they go right back up to where they think they are supposed to stop.

Sounds like somebody replaced the wiper motor at some point and got the arm that attaches to the motor 180 out. Been there, my brother did that...

There's a contact in the motor (the park switch) that supplies power to the motor when the blades are not in the park position. Both the park switch and the dash switch must be off for the motor to stop.

I assume they always stop at the same place? If so, the park switch is working but the location of "park" is somehow messed up. If they stop anywhere, the park switch is broken (always open).

Sounds like MathMan has the solution, but I'd think it would have to be set to 90 degrees off to stop in the middle. The motor goes around and around, and I think the left position is 180 degrees from the right position.

i looked under the dash, the retaining nut on the motor looks like its not tight, i can see threads inside the nut. unless thats the way it is. what does the stud look like, is it splined? square? it doesnt look like they are 90 or 180 off watching the motor, but they do stop in the same spot all the time.

If I remember correctly the shaft has a square or rectangle that the arm fits on. On my J-10, it was doing exactly like you describe - and my brother told me it had been that way after he had replace the motor. Took the nut off, removed the arm, moved the wipers to the real 'park' position, got the arm back on the wiper, and replaced the nut. Wipers have parked where they're supposed to since.

It sounds like your Jeep has spotted a younger hot jeep (maybe one of those pink barbie model)

That is making it's wipers pop-up.

Now you know why they call these cars Woodies ! It's not the faux wood trim.

Would it be possible to turn them off, then remove the arms from the pivots and put them back on at the position where you want them to be "parked?"
