The rear wiper system is a fixed-cycle wiper system. A single switch in the instrument panel center bezel controls both the rear wiper and washer functions.

We install LED headlights and off-road lights with an sPOD switch panel on our 2005 Jeep Wrangler Unlimited.

You need to make sure the connectors at the switches are in good shape. If they aren't, find a junkyard that has the wires, connectors, and the switch panel and replace them all.
