One of our work Jeep Libs, a 2003, its rear door/glass started malfunctioning after a couple years in service. Would close the gate and glass would bonk against the latch mech. inside the door. Took off the interior cover to the gate and kept a screwdriver in the back for releasing the spring in the latch mechanism. Not sure on the mech. terms, but seemed a slot between flanges on the latch unit we easily pryed would release spring tension and latch mech. would swivel/accuate to accept window latch. This problem was intermittent and went on for years stringing along on this truck. At the least, was a good field remedy. This wasnt my primary shift truck, so I dont know and doubt if it was diagnosed or even repaired correctly ever to tell you any final, proper resolution. But, of course we lost the plastic interior gate piece in the shop somewhere so it stayed open/exposed for good.
