Headlight Wiper/Washer

General Description

The circuit consists of the starter switch, headlight
wiper switch, headlight wiper motor and washer
motor. By pushing the headlight wiper/washer switch
with the starter switch on, the wiper will make 5
strokes with washer solution applied between each
of the first 4 strokes, regardless of the length of time
the switch is held down.
The washer nozzle is installed to the wiper blade, and
the tank to which the washer motor is installed shared
between the headlight washer and the windshield
washer.
