NOTE:

The washer hose is a component within the body wiring harness conduit. The washer hose is a hard plastic convoluted tube that could be wrapped with electrical tape along the main body electrical wiring harness. It starts underhood where it is connected to the windshield washer nozzle hose. The washer hose routes into the main body wiring harness underhood and passes through the front of the air inlet grille. The washer hose is routed inside the vehicle interior behind the left front side window garnish molding, along the floor pan area and continues to the rear of the vehicle, as equipped. The washer hose could be routed back to the center of the vehicle where it could possibly connect to the high mounted stop lamp where it connects by rubber flexible tubing.

Locate the damaged section of the washer hose.
If the leak is located inside the main body wire harness, carefully cut the electrical tape, securing the harness within the electrical conduit to expose the damaged section of washer hose.
Cut and remove the damaged section of the washer hose.
