When the ignition SW turned on, the current from the WIPER fuse flows to the front wiper and washer SW TERMINAL 17,
and the front wiper motor TERMINAL 2.
1. Low Position
When the front wiper SW is turned to LO position, the current flows from the front wiper and washer SW TERMINAL 17 to
TERMINAL 7 to the front wiper motor TERMINAL 1 to TERMINAL 5 to GROUND, and operates the front wiper motor at low
speed.
2. High Position
When the front wiper SW is turned to HI position, the current flows from the front wiper and washer SW TERMINAL 17 to
TERMINAL 8 to the front wiper motor TERMINAL 4 to TERMINAL 5 to GROUND, and operates the front wiper motor at high
speed.
3. INT Position
When the front wiper SW is turned to INT position, the relay operates and the current which is connected by the relay
function flows from the front wiper and washer SW TERMINAL 17 to TERMINAL 2 to GROUND, and operates the wipe.
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 to change the charging time of the condenser.
4. Washer Interlocking Operation
When the front washer SW is pulled up, the current flows from the washer motor TERMINAL 2 to TERMINAL 3 to the front
wiper and washer SW TERMINAL 11 to TERMINAL 2 to GROUND, operates the washer motor and the window washer
emits a water spray. This causes the current to flow to the washer continuous operation circuit in the front wiper and washer
SW TERMINAL 11 to TERMINAL 7 to front wiper motor TERMINAL 1 to TERMINAL 5 to GROUND, and operates the wiper.

When the ignition SW is turned on, the current flows from the WASHER fuse to washer motor TERMINAL 2, and the current
flows from the RR WIPER fuse to rear wiper relay TERMINAL 3, and the rear wiper motor TERMINAL 1 respectively.
1. Rear Wiper Normal Operation
When the ignition SW is turned on, and the rear wiper and washer SW is turned to ON position, the current flows from the
rear wiper relay TERMINAL 3 to TERMINAL 6 to the rear wiper and washer SW TERMINAL 10 to TERMINAL 2 to
GROUND, and turns on the rear wiper relay. As a result, the current flows from the rear wiper relay TERMINAL 3 to
TERMINAL 4 to the rear wiper motor TERMINAL 3 to TERMINAL 2 to GROUND, and operates the rear wiper.
2. Rear Wiper Intermittent Operation
When the ignition SW is turned on, and the rear wiper and washer SW is turned to INT position, the current flows from the
rear wiper relay TERMINAL 3 to TERMINAL 2 to the rear wiper and washer SW TERMINAL 13 to TERMINAL 2 to
GROUND, and the intermittent circuit in the rear wiper relay is controlled to operate the wiper intermittently.
3. Washer Operation
When the ignition SW is turned on, and the rear wiper and washer SW is turned from OFF to WASH position, the current
flows from the WASHER fuse to the washer motor TERMINAL 2 to TERMINAL 1 to the rear wiper and washer SW
TERMINAL 12 to TERMINAL 2 to GROUND. This activates the washer motor, and the window washer emits a water spray.
When the rear wiper and washer SW is turned to ON position, the window washer emits a water spray during rear wiper
normal operation.
