REAR WASHER NOZZLE (Continued)

OPERATION

The rear washer nozzle is designed to dispense
washer fluid into the wiper pattern area on the out-
side of the liftglass. Pressurized washer fluid is fed to
the nozzle from the washer reservoir by the rear
washer pump/motor through a single hose, which is
attached to a barbed nipple on the back of the rear
washer nozzle behind the rear wiper motor trim
cover on the inside of the liftglass. A fluidic matrix
within the washer nozzle causes the pressurized
washer fluid to be emitted from the nozzle orifice as
a fan-like stream to more effectively cover a larger
area of the glass to be cleaned.

REMOVAL

(1) Remove the trim cover from the rear wiper
motor on the inside of the liftglass. (Refer to 8 -
ELECTRICAL/REAR
WIPER MOTOR TRIM COVER - REMOVAL).
(2) From the inside of the liftglass, disconnect the
rear washer supply hose from the barbed nipple on
the back of the rear washer nozzle (Fig. 9).
