GENERAL DESCRIPTION
AND SYSTEM OPERATION
WINDSHIELD WIPER SYSTEM
The windshield wiper system consists of a wiper motor, a
linkage, a wiper arm and a blade, and a wiper/washer
switch. The windshield wiper circuit incorporates a self–
parking device which consists of a worm gear and a cam
plate in order to keep the circuit engaged temporarily when
the switch is turned off. The wiper system is driven by a
permanent magnet–type motor. The windshield wiper mo-
tor is mounted on the dash panel and is directly connected
to the windshield wiper linkage.
The windshield wiper motor has two speeds, LO and HI,
and also has intermittent wiper capability. The wiper
switch is an integral part of the wiper/washer switch. Wind-
shield wiper operation is actuated through the lever on the
right side of the steering column.
WINDSHIELD WASHER SYSTEM
The windshield washer system is equipped with a washerfluid reservoir, a washer fluid pump, hoses, nozzles, and
a wiper/washer switch. The windshield washer reservoir
is mounted behind the front left wheel well splash shield.
Attached to the reservoir is a washer pump, which pumps
fluid through the hoses to the two nozzles mounted on the
hood. The washer switch is an integral part of the wiper/
washer switch. Windshield washer operation is actuated
through the lever on the right side of the steering column.
REAR WINDOW WIPER/WASHER
SYSTEM
The rear window wiper system consists of a wiper motor,
a wiper arm, and a blade. The rear window wiper motor is
located inside the hatchback/tailgate door and is directly
connected to the rear window wiper. The rear window
washer system is equipped with a separate washer fluid
pump and hose. The hatchback has a hatch–mounted
rear window washer nozzle and on the wagon, the washer
nozzle is incorporated into the rear wiper motor. The rear
window washer reservoir is mounted behind the front left
wheel well splash shield. Attached to the reservoir is a
washer pump, which pumps fluid through a hose to the
rear washer nozzle.
