ZJ tailgate
My 98 ZJ's got some wiring issues. The rear wiper, rear defrost and license plate lights don't work. The power lock functions properly. Any ideas of where to look for a disconnect?

Check the wire bundle where it comes out of the roof. There could be broken wires in the bundle. This harness twists and flexes every time you open the hatch. Does your "cyclops" brake light work?

3rd brake light is fine. I checked at the hinges and the wires look good. It could be a coincidence that the three components are out of commission. I'll run some electrical tests on the harnesses tonight.
