With the ignition SW turned on, the current flows to TERMINAL 17 of the front wiper and washer SW, TERMINAL 2 of the
front wiper motor through the WIPER fuse, the current flows to TERMINAL 1 of the washer motor through WASHER fuse.
1. Low Speed Position
With the wiper SW turned to LOW position, the current flows through TERMINAL 17 of the front wiper and washer SW to
TERMINAL 7 to TERMINAL 1 of the front wiper motor to TERMINAL 5 to GROUND and causes the wiper motor to run at low
speed.
2. High Speed Position
With the wiper SW turned to HIGH position, the current flows through TERMINAL 17 of the front wiper and washer SW to
TERMINAL 8 to TERMINAL 4 of the front wiper motor to TERMINAL 5 to GROUND and causes the wiper motor to run at
high speed.
3. INT Position
With the wiper SW turned to INT position, the relay operates and the current which is connected by relay function flows
through TERMINAL 17 of the front wiper and washer SW to TERMINAL 2 to GROUND. This flow of current operates the
intermittent circuit and the current flows through TERMINAL 17 of the front wiper and washer SW to TERMINAL 7 to
TERMINAL 1 of the front wiper motor to TERMINAL 5 to GROUND and the wiper functions.
The intermittent operation is controlled by a condenser's charged and discharged function installed in the relay and the
intermittent time is controlled by a time control SW to charge the charging time of condenser.
4. Washer Continuous Operation
With the washer SW pulled to on, the current flows through TERMINAL 1 of the washer motor to TERMINAL 2 to TERMINAL
11 of the front wiper and washer SW to TERMINAL 2 to GROUND and causes the washer motor to run and the window
washer to jet. This causes the current to flow to washer continuous operation circuit in TERMINAL 17 of the front wiper and
washer SW to TERMINAL 7 to TERMINAL 1 of the front wiper motor to TERMINAL 5 to GROUND and the wiper functions.
