WINDSHIELD WIPER/WASHER AND REAR WIPER/WASHER
GENERAL DESCRIPTION
~ The circuit consists of the starter switch, wiper & washer switches, wiper motors, washer motors and inter­
mittent relays for both the windshield and some models the rear wipers.
When the
wiper & washer switch is turned on with the starter switch on, the battery voltage is applied to the
wiper motor to activate the wiper.
The washer
motor squirts glass cleaning fluid while the washer switch is being pushed. The intermittent relay
is used
to control motion of the wiper.
