Anybody here have wiring diagrams for 97+ and willing to look up wire colors for the rear wiper and washer circuits? Neither of mine work, switch is putting voltage through the fuse, want to check the wires in the cargo panel that's already off before diving into the motor

First thing to check is the tailgate wire harness. Visually inspect the harness and test wire continuity from the wiper motor plug to the body side wire harness plug. Failure of the tailgate wire harness at or near the hinges is almost as common as the driver door wire harness failures.

Thanks Tim. I pulled the hatch cover and the motor is getting current, need to investigate more.

Check continuity on your grounds between the motor and where it connects to the body inside the cargo area too.

The problem was the relay load wire was broken. Good current on the relay control circuits but the dead wire was load side. Bypassed the wire and all is well.
