I have a 2011 Nissan Pathfinder LE. The rear defrost and the rear wiper do not work. I have checked the fuses and they are intact. The two power terminals on the back window are still connected for the defrost system. How do I locate the source of the problem? Are the problems connected or just a coincidence that they are located right next to each other?
Find the ground connection. That is usually a black wire and it is attached to a screw someplace close. You might find a broken ground wire or a corroded screw. The ground may pass through the wire conduit from the body to the rear hatch door. Check that area for a broken wire. You may have to remove interior panels to find it.
