Windshield Wiper/Washer
General Description
The circuit consists of windshield wiper/washer
switch, windshield wiper motor, windshield washer
motor and alarm & relay control unit.
When windshield wiper/washer switch is turned on
with starter switch on, battery voltage is applied to
windshield wiper motor to activate wipers.
When windshield washer switch is turned on with

Rear Wiper/Washer
General Description
The circuit consists of rear wiper/washer switch,
alarm & relay control unit, rear wiper motor and rear
washer motor.
When rear wiper switch on rear wiper/washer
switch is depressed, battery voltage is applied to
rear wiper motor through alarm & relay control unit
and activates rear wiper motor.
When rear washer switch on rear wiper/washer
switch is depressed, battery voltage is applied to
rear washer motor and activates rear washer motor.
At the same time, the current as an input signal for
activating rear wiper motor flows to alarm & relay
control unit, then alarm & relay control unit
activates rear wiper motor to wipe glass cleaning
fluid.
