WITH THE IGNITION SW TURNED ON, THE CURRENT FLOWS TO TERMINAL 17 OF THE FRONT WIPER AND WASHER SW, TERMINAL
2 OF THE FRONT WASHER MOTOR AND TERMINAL 6 OF THE FRONT WIPER MOTOR THROUGH THE WIPER FUSE.
1. LOW SPEED POSITION
WITH WIPER SW TURNED TO LOW POSITION, THE CURRENT FLOWS FROM TERMINAL 17 OF THE FRONT WIPER AND WASHER SW
" TERMINAL 7 "TERMINAL 3 OF THE FRONT WIPER MOTOR "WIPER MOTOR "TERMINAL 1 "TO GROUND AND CAUSES THE
FRONT WIPER MOTOR TO RUN AT LOW SPEED.
2. HIGH SPEED POSITION
WITH WIPER SW TURNED TO HIGH POSITION, THE CURRENT FLOWS FROM TERMINAL 17 OF THE FRONT WIPER AND WASHER SW
"TERMINAL 8 "TERMINAL 2 OF THE FRONT WIPER MOTOR "WIPER MOTOR "TERMINAL 1 "TO GROUND AND CAUSES THE
FRONT 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 17 OF THE FRONT WIPER AND WASHER SW "TERMINAL 2 "TO GROUND. THIS FLOW OF
CURRENT OPERATES THE INTERMITTENT CIRCUIT AND THE CURRENT FLOWS FROM TERMINAL 17 OF THE WIPER AND FRONT
WASHER SW "TERMINAL 7 "TERMINAL 3 OF THE FRONT WIPER MOTOR "WIPER MOTOR "TERMINAL 1 "TO GROUND AND
OPERATES THE WIPER.
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 CHANGE THE CHARGING TIME OF THE
CONDENSER.
4. WASHER CONTINUOUS OPERATION (W/ INT CONTROL)
WITH WASHER SW TURNED TO ON, THE CURRENT FLOWS FROM TERMINAL 2 OF THE FRONT WASHER MOTOR "TERMINAL 1 "
TERMINAL 11 OF THE FRONT WIPER AND WASHER SW "TERMINAL 2 "TO GROUND AND CAUSES TO THE FRONT WASHER
MOTOR TO RUN. AND THE WINDOW WASHER EMITS A WATER SPRAY. THIS CAUSES THE CURRENT TO FLOW TO WASHER
CONTINUOUS OPERATION CIRCUIT IN TERMINAL 17 OF THE WIPER AND WASHER SW "TERMINAL 7 "TERMINAL 3 OF THE
FRONT WIPER MOTOR "WIPER MOTOR "TERMINAL 1 "TO GROUND AND OPERATES THE WIPER.

WHEN THE IGNITION SW IS TURNED ON, CURRENT FLOWS TO TERMINAL 2 OF THE REAR WASHER MOTOR, TERMINAL 3 OF THE
REAR WIPER RELAY AND TERMINAL 1 OF THE REAR WIPER MOTOR THROUGH THE WIPER FUSE.
1. REAR WIPER NORMAL OPERATION
WITH THE IGNITION SW TURNED ON AND REAR WIPER AND WASHER SW TURNED ON, THE CURRENT FLOWING TO TERMINAL 3
OF THE REAR WIPER RELAY FLOWS TO TERMINAL 6 OF THE RELAY "TERMINAL 10 OF THE REAR WIPER AND WASHER SW "
TERMINAL 2 "TOGROUND. THUS, THE RELAY COIL IS ACTIVATED AND THE CURRENT TO TERMINAL 3 OF THE RELAY FLOWS TO
TERMINAL 4 " TERMINAL 4 OF THE REAR WIPER MOTOR " MOTOR "TO GROUND AND CAUSES THE MOTOR TO OPERATE THE
WIPER.
2. REAR WIPER INTERMITTENT OPERATION
WHEN THE IGNITION SW IS ON AND THE REAR WIPER AND WASHER SW IS TURNED TO INT POSITION, CURRENT FLOWING TO
TERMINAL 3 OF THE REAR WIPER RELAY FLOWS TO TERMINAL 2 OF THE RELAY "TERMINAL 13 OF THE REAR WIPER AND
WASHER SW "TERMINAL 2 "GROUND.
THIS CAUSES THE MOTOR TO OPERATE (THE POINT CHANGES) AND THE INTERMITTENT CIRCUIT OF THE RELAY OPERATES.
INTERMITTENT OPERATION OF THE CIRCUIT IS CONTROLLED BY THE CHARGING AND DISCHARGING OF THE CONDENSER
INSTALLED INSIDE THE RELAY.
3. WASHER OPERATION
WITH THE IGNITION SW TURNED ON AND THE REAR WIPER AND WASHER SW TURNED TO ON POSITION, WHEN THE WIPER SW IS
TURNED FURTHER, THE CURRENT FLOWING TO TERMINAL 2 OF THE REAR WASHER MOTOR FLOWS TO TERMINAL 1 OF THE
MOTOR "TERMINAL 12 OF THE REAR WIPER AND WASHER SW "TERMINAL 2 "TO GROUND SO THAT THE WASHER MOTOR
ROTATES AND THE WINDOW WASHER EJECTS THE SPRAY, ONLY WHILE THE SWITCH IS FULLY TURNED.
WHEN THE WIPER SW IS OFF AND THEN TURNED TO WASHER ON (WIPER OFF SIDE), ONLY THE WASHER OPERATES.
