System Outline

With the ignition SW turned on, the current flows to TERMINAL 8 of the wiper and washer SW, TERMINAL 2 of the front
wiper motor through the WIPER fuse, and the current flows to TERMINAL 2 of the washer motor through the WASHER fuse.

1. Low Speed Position

With wiper SW turned to LO position, the current flows from TERMINAL 8 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 to the front wiper motor to run at low
speed.

2. High Speed Position

With wiper SW turned to HI position, the current flows from TERMINAL 8 of the front wiper and washer SW to TERMINAL 9
to TERMINAL 4 of the front wiper motor to TERMINAL 5 to GROUND and causes to the wiper motor to run at high speed.

3. INT Position

With wiper SW turned to INT position, the relay operates and the current which is connected by relay function flows from
TERMINAL 8 of the front wiper and washer SW to TERMINAL 5 to GROUND. This flow of current operates the intermittent
circuit and the current flows from TERMINAL 8 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 functions.
The intermittent operation is controlled by the charge/discharge function of the condenser installed in the relay, and the
intermittent time is controlled by a time control SW (w/ intermittent volume SW) to change the charging time of the
condenser.

4. MIST Position

With wiper SW turned to MIST position, the current flows from TERMINAL 8 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 to the front wiper motor to run at low
speed.

5. Washer Continuous Operation

With the washer SW turned to on, the current flows from TERMINAL 2 of the washer motor to TERMINAL 1 to TERMINAL 4
of the front wiper and washer SW to TERMINAL 5 to GROUND and causes to the washer motor to run, and the window
washer jet operates. This causes the current to flow to washer continuous operation circuit in TERMINAL 8 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 washer
operates continuously.
