Repair Procedure/Information
1)
Check the washer nozzle for contamination. If the spray hole is clogged with wax, dust or foreign material, blow compressed air to the spray hole
of the washer nozzle to clear the obstruction.
2)
Check the washer nozzle fluid hose. Make sure the hose is not pinched, and that it does not have severe bends or kinks.
3)
Check the rear washer hose running along the left sill, as well as the hose in the tailgate area, to ensure that the hose is not pinched or bent,
restricting the flow.
