Grand Cherokee 4WD V8-5.2L VIN Y (1998)
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 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
snapped 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 left side body wire harness.
Above the liftgate opening the hose connects to a check valve, which prevents washer fluid drain-back or siphoning from occurring. From the
check valve, another single hose is routed through grommets in holes in the upper liftgate opening panel and the lift-gate inner panel to the washer
nozzle. The washer nozzle snaps into a hole in the liftgate outer panel, above the liftgate glass.
The rear washer nozzle cannot be adjusted. The nozzle, check valve, and hose fittings cannot be repaired and, if faulty or damaged, they must be
replaced.
