Been searching and can't really find an answer...
I have a 94 Cherokee, and the rear wiper arm is loose. When I turn it on, it might swipe once or twice, but then falls down and just hangs down on the tailgate. If I put it back and pound on the base of the arm with my fist, it'll swipe a couple times then fall again. I haven't tried to take it apart yet, does it have a nut or clip that might be loose, or is it most likely stripped and I need a whole new motor? Thanks!!

 

I'm pretty sure there is a nut right at the base of the wiper where it pivots, and i'm not positive, but it may tighten that up? Also, I'm speaking of what i've seen from my 97, so I'm not positive if there is a difference between years.

 

Ok thanks I'll check that. I think they are pretty much the same thru 97.

 

Also If that still doesn't help remove the same screw and check if the groves on the shaft are stripped also inside of the wiper are. I had someone playing with my rear wiper and they stripped it out.

 

Yeah, that's actually what happened to mine... I just took it off
