Windshield Washer Hose: Description and Operation
Wipers and Washers-Rear Washer Hose
Fluid for the rear washer is supplied by a two-way washer pump located in the windshield washer fluid reservoir in the engine compartment.
The rear washer hose contains a check valve, which is located in the hose that passes through the liftgate in the rear of the vehicle. This check valve
holds the entire line full of washer fluid between washer operation. There is also a stand pipe located along the right hand D-pillar of the vehicle. This
stand pipe prevents the unintentional release of washer fluid from the rear washer nozzle. If the hose is cut or disconnected after the line was initially
primed with fluid, and the washer system is turned on, the stand pipe may fill with fluid. To resolve this, once the hose is repaired, temporarily
disconnect the check valve to allow fluid in stand pipe to drain to lowest point in the hose; then reinstall the check valve.
