1997 Jeep Grand Cherokee Repair Question
My rear window wiper stops at one swipe and does not move.
Never worked on a rear motor but it sounds exactly like the many I've fixed for that on the front. When the motor should be running, use a grounded test light to check for voltage on the metal case of the motor. If you find any, look for that motor to be mounted to the plate on rubber inserts, and for a brass grounding strap riveted to the plate and going under one of the mounting bolt heads. They arc a burned ring around the head, then stop working when that plate flexes and creates the intermittent connection. I can't remember if the rear motor is mounted like that, but the front ones always are to reduce vibration. If that's what you find, look for a place to attach a new ground wire, or drill a small hole in the plate and run in a self-tapping screw, then attach the other end of that ground wire to the body. Some older motors had the switch plate held on with five screws. You can use one of them to attach the wire to. That plate is riveted on newer motors.

Thanks will give it a try. Rear wiper motor is indeed mounted with two bolts thru rubber grommets, one to a plate and one thru frame of rear door.
