Windshield Washer Spray Nozzle: Description and Operation
Fig. 8 Washer Nozzle
The two washer nozzles have integral snap features and an anti-rotation tab that secure them in dedicated holes in the cowl plenum cover/grille panel
located near the base of the windshield . The domed upper surface of the washer nozzle is visible on the top of the plenum cover/grille panel, and the
nozzle orifice is oriented towards the windshield glass. The washer plumbing fittings for the washer nozzles are concealed beneath the cowl plenum
cover/ grille panel. These fluidic washer nozzles are constructed of molded plastic. The cowl plenum cover/ grille panel must be removed from the
vehicle to access the nozzles for service. The washer nozzles cannot be adjusted or repaired. If faulty or damaged, they must be replaced.
The two washer nozzles are designed to dispense washer fluid into the wiper pattern area on the outside of the windshield glass. Pressurized washer fluid
is fed to each nozzle from the washer reservoir by the washer pump/motor unit through a single hose, which is attached to a barbed nipple on each
washer nozzle below the cowl plenum cover/grille panel. The washer nozzles incorporate a fluidic design, which causes the nozzle to emit the
pressurized washer fluid as an oscillating stream to more effectively cover a larger area of the glass area to be cleaned.
