FRONT

Pressurized washer fluid is fed through a single hose, attached to a barbed nipple on the washer pump. The hose is routed from the washer reservoir to the dash panel along the top of the right front wheelhouse inner panel. At the dash panel, the hose passes 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 wye fitting near the passenger side washer nozzle. Hoses from the wye fitting are routed to the two washer nozzles, which are snap-fit into openings in the cowl plenum cover/grille panel.

The wye fitting includes an integral check valve to prevent the washer fluid from draining from the nozzles back to the reservoir or from leaking out of the nozzles after washer operation is complete. 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 washer reservoir to the dash panel along the top of the right front wheelhouse inner panel. At the dash panel, the hose passes through a grommet in the dash panel into the passenger compartment. Inside the passenger compartment the hose is routed down the right cowl side inner panel to the sill, then along the sill to the right quarter inner panel. The hose is routed along the quarter inner panel and up the right liftgate opening pillar to the liftgate opening header.

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 liftgate, 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.
