Grand Cherokee 2WD L6-4.0L VIN S (1997)
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
snap-fit into openings in the cowl plenum cover/grille panel, below the windshield.
The two fluidic washer nozzles are not adjustable. The nozzles and tee 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 holes and grommets in the upper liftgate opening panel and the liftgate inner panel to the washer
nozzle. The nozzle is snap-fit into an opening in the liftgate outer panel, above the liftgate glass.
The washer nozzle is not adjustable. The nozzle and check valve cannot be repaired and, if faulty or damaged, they must be replaced.
