Wj Rear wiper issue

So I'm having this odd issue with my rear wiper. I've put 2 brand new, not even remanned, wiper motors in because for some reason when it's cold my wiper struggles to even make it a quarter of the way up the window before slamming back down to park position, sometimes it tries, gets to half way, and then EVENTUALLY makes it all the way before stalling out again. What really bothers me is the fact that if it only makes it half way then stalls there, if I turn the switch off it will work hard to get back to park position and just slam down, but it can't wipe the whole window if the switch is on.
Now with those 2 new motors, it has a new arm assy and blade. This is starting to get aggravating not being able to see out my rear window with this slushy snow we have most of the time.

Has anyone else had this issue before? or do I just deal with it.

When you turn your rear wiper on, do the interior lights above the console glow dimly?

No they don't. Wish I could post a video of this cause it's extremely annoying not being able to see out the back window

I asked you that because when my 2000 WJ rear wiper motor failed almost the same as yours does, the overhead cab lights would light up very dimly when I tried to use the rear wiper. After a couple rear wiper motor swaps and the same symptoms, it turned out to a shorted hot pink wire in the harness running along my driver side floor board. After I found the short and cleanly spliced the wire back together, my rear wiper worked perfectly, and so did my interior lights.

See this is why I'd love to post a video. My wiper works, but is very sporadic. Like it will continually swipe a quarter of the glass, then move to half glass, then maybe make it all the way and start only wiping that side of the glass, then I'll shut the switch off and it'll slam back to park. And other times it swipes a little tiny bit of the glass, then slam back to park and not move even with the wiper switch on, then I play with the switch for about 30 seconds and it'll work again. It's almost like there's too much resistance between the glass and the blade so the motor overheats and goes into some sort of protective shut down.

If you turn on the wiper and pull the arm away from the glass so there is no resistance, does it still struggle?
The motors are famous for seizing up completely from internal corrosion, debris and time. Especially in salt-use areas....but your replacements have been new?

It sounds like it needs to be removed, cleaned and reinstalled before it burns itself up and has to be replaced.
If you did 2 swaps already, it sounds like there's something getting in them to make them struggle or they're installed with resistance somehow.
I would pull the current motor and see if it sweeps with no problem while just connected electrically.

Pull the switch and bypass it to see if the wiper operates normally.

They've both done this right from the get go. When it's warm out if Works no problem but as soon as it gets cold it stops working properly

I would suspect the stalk switch then.

But would it do that only in the cold? If it were happening more often I'd suspect that too but being that it works fine when it's warm outside makes me think the stalk is fine.

With heat, the contacts on either end could be at issue but the key to me is "I play with the switch for about 30 seconds and it'll work again."

Especially if the behavior also occurs with the motor unmounted and plugged in, with 2 different motors.

It sounds like a broken connection along the wiring path would be easier than taking apart the stalk or even replacing it.

Now it gets even weirder. Now that it's above 0*C here, the damn thing is working totally fine again. No skipping, no stalling, clearing the entire window and going back to park position. I don't understand this but it's getting frustrating that it stops working when I need it the most.

Connector pin wipe out of spec. 20 years of vibration will do that. The change in operation with the temperature is the clue. Heats up, works again because the connector is making better contact. Check pins for corrosion or varnish from arcing, crush connectors together to improve wipe pressure, or just eliminate the connector, hard wire the motor and never have to worry about it again.

Does your rear wiper have the rubber boot/grommet that goes over the wiper arm shaft that goes into the hatch? Could possibly be that boot when its cold it shrinks creating a large amount of resistance and possibly jamming the wiper motor/arm in the process...look into it, sounds stupid but is the only thing I could think of outside of an internal short somewhere, but if it works fine in warm weather then its most likely nothing to do with the wiring or motor.
