Washer nozzle and plumbing

FRONT

Pressurized washer fluid is fed through a single hose, attached to a barbed nipple on the front washer pump. The hose is routed to a tee fitting located in the cowl plenum area, beneath the cowl plenum cover/ grille panel. Hoses from the tee fitting are routed to the two nozzles, which are riveted into openings in the cowl plenum cover/grille panel below the windshield.

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 washer pump. The hose is routed from the front of the vehicle to the liftgate with the body wire harness.

Located at the highest point of the supply hose routing, beneath the liftgate opening upper header garnish moulding, 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 through a grommet to the liftgate, where it is connected to a nipple that protrudes from the inside of the rear wiper motor output shaft bezel.

The washer fluid passes through the bezel nipple to the outside of the liftgate. There a single hose is connected to a nipple on the outside of the rear wiper motor output shaft bezel. The hose is routed through a plastic trough-like guard snapped to the underside of the rear wiper arm. The hose is then attached to the single rear washer nozzle. The nozzle snaps into place on the rear wiper arm.

The rear washer nozzle cannot be adjusted. The nozzle, bezel, check valve, and hose fittings cannot be repaired and, if faulty or damaged, they must be replaced.
