Windshield Washer Spray Nozzle: Description and Operation
SYSTEM OPERATION
Front
Pressurized washer fluid is fed through a single hose, attached to a barbed nipple on the washer pump. The hose is routed through a grommet
inserted in a hole in the cowl plenum panel to an in-line fitting located in the cowl plenum area, beneath the cowl plenum cover/grille panel.
A hose from the in-line fitting in the cowl plenum is routed through clips molded into the underside of the cowl plenum cover/grille panel to a Y
fitting near the passenger side washer nozzle. Hoses from the Y fitting are routed to the two washer nozzles, which are snap-fit into openings in the
cowl plenum cover/grille panel.
The two fluidic washer nozzles are not adjustable. The nozzles and hose fittings cannot be repaired and, if faulty or damaged, they must be
replaced.
Rear
Pressurized washer fluid is fed through a single hose, attached to a barbed nipple on the rear window washer pump. The hose is routed from the
reservoir up the right liftgate opening pillar to the liftgate opening header with the body wire harness.
Located near the top of the supply hose routing, beneath the right liftgate opening pillar trim, the hose connects to a check valve. The check valve
prevents washer fluid drain-back or siphoning from occurring. From the check valve, another single hose is routed to the liftgate opening header
panel. There the hose passes through a grommet out of the liftgate opening header and through another grommet into the top of the liftgate inner
panel. Within the lift-gate, the hose is connected to a nipple that protrudes from the fluidic washer nozzle, which is snap-fit into a keyed hole in the
top of the liftgate outer panel.
The rear window washer nozzle cannot be adjusted. The nozzle, check valve, and hose fittings cannot be repaired and, if faulty or damaged, they
must be replaced.
