Hey been having some issues in the rear wiper of my wj. it works when it wants to and generally stops in the middle of the window or hooks under the window. anyone else have issues similar to this? not sure if it is a connection thats bad or whether the motor needs to be replaced.

 

About the hooking under the glass. My ZJ had the same problem, but it was because someone used the wrong wiper arm. The proper arm is shaped so that it rides up off the glass on a plastic ramp thingy as it parks. Stopping in the middle of the window shows the parking switch is faulty and sometimes not working is bad connections or broken wires in the harness above the window.
