Rear Washer Hose Routing
The rear washer hose is a component of the main body wire harness assembly. The rear washer hose is a hard plastic convoluted tube that is wrapped in
the electrical tape along with the main body wiring harness. It starts underhood where it connects to the rear washer solvent container hose, this is rubber
tubing. The rear washer hose routes into the main body wire harness underhood and passes through the front of the dash. The rear washer hose runs
inside the vehicle interior along the left side rocker and over the left rear wheel housing. The rear washer hose is then routed up the left side pillar where
it connects to the rear washer nozzle hose, where it is rubber tubing, at the top of the lift gate opening.
Removal Procedure
1. Locate the damaged section of the rear washer hose, this will be hard plastic convoluted tubing.
2. If the leak is located inside the main body wire harness, cut back the wire harness electrical tape to expose the damaged section.
3. Cut out the damaged section of the rear washer hose.
Installation Procedure
