a washer tank, a washer motor, twowasher nozzles, and connecting hoses. Both systems are then connected
to a wiper lever and a timer unit in steering column combination switch.
• Hoses
Washer hoses are neoprene lines that carry washer fluid to washer nozzles. There are three hose pieces, a
three-port hose joint, and a two-port hose joint. Hoses can be replaced individually. Washer hose system
also has three replaceable hold-down clips.

mechanism. It is a replaceable item.
• Nozzles
Washer nozzles deliver washer fluid directly to windshield. Nozzles are replaceable as an individual item.
• Tank assembly
Washer tank assembly stores washer fluid used by washer system. It is a plastic assembly with a fill port

Wiper system
• Arm
Wiper arms are metal arms which pull wiper blades across windshield. They are spring-loaded to firmly hold
blades onto windshield during operation of wiper system. They are individual units consisting of a drive's
side and a passenger side arm.
• Blades
Wiper blades are metal frames with rubber inserts. They are available as a unit, or inserts can be replaced
separately.
• Link assembly
Wiper link assembly connects wiper motor to wiper arms. It consists of two connecting rods and two pivot
units. When inoperation, assembly converts wiper motor's rotational motion into proper left/right movement
needed by wiper arms. If faulty, it can be disassembled, but replacement of full assembly is recommended.
• Motor and bracket
Motor is a 12V DC, two-speed unit which provides power to wiper system. It is connected to a transmission
(gear box) in mounting bracket which reduces motor rpm and increases torque. This low rpm, high torque
motion is then transmitted to wiper link assembly. Motor and bracket are a single, replaceable item.
Circuit operation
Front wiper & washer operation (Low and high positions)
When the ignition switch is turned to "ON" or "START" position battery voltage is applied to front wiper &
washer switch terminal A (L) of D-01 and front wiper motor terminal F (L/W) of D-02. In the 'HI' position of the
wiper & washer switch, battery voltage is applied to the wiper motor terminal E(R/W) of D-02, In the 'LO'
position wiper& washer switch C(G) of D-02. The wiper motor has separate brushes and windings for low and
high speed operation. When the wiper & washer switch is in "LO" or "HI" position, one of the brushes is
