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
starter switch on, battery voltage is applied to
windshield washer motor.
Windshield washer motor squirts glass cleaning
fluid while windshield washer switch is pushed and
at the same time, alarm & relay control unit activates
windshield wiper motor to wipe glass cleaning fluid
at low speed.
