WITH THE IGNITION SW TURNED ON, THE CURRENT FLOWS TO TERMINAL 18 OF THE WIPER AND WASHER SW, TERMINAL 2 OF
THE 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 18 OF THE WIPER AND WASHER SW "
TERMINAL 7 " TERMINAL 3 OF THE FRONT WIPER MOTOR " TERMINAL 1 " TO GROUND AND CAUSES TO THE WIPER MOTOR TO
RUN AT LOW SPEED.
2. HIGH SPEED POSITION
WITH WIPER SW TURNED TO HIGH POSITION, THE CURRENT FLOWS FROM TERMINAL 18 OF THE WIPER AND WASHER SW "
TERMINAL 13 " TERMINAL 2 OF THE FRONT WIPER MOTOR " TERMINAL 1 " 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 18 OF THE WIPER AND WASHER SW " TERMINAL 16 " TO GROUND. THIS FLOWS OF
CURRENT OPERATES THE INTERMITTENT CIRCUIT AND THE CURRENT FLOWS FROM TERMINAL 18 OF THE WIPER AND WASHER
SW " TERMINAL 7 " TERMINAL 3 OF THE FRONT WIPER MOTOR " TERMINAL 1 " TO GROUND AND FUNCTIONS.
THE INTERMITTENT OPERATION IS CONTROLLED BY A CONDENSER'S CHARGED AND DISCHARGED FUNCTION INSTALLED IN
RELAY AND INTERMITTENT TIME IS CONTROLLED BY A TIME CONTROL SW TO CHARGE THE CHARGING TIME OF THE
CONDENSER.
4.MIST POSITION
WITH WIPER SW TURNED TO MIST POSITION, THE CURRENT FLOWS FROM TERMINAL 18 OF THE WIPER AND WASHER SW "
TERMINAL 7 " TERMINAL 3 OF THE FRONT WIPER MOTOR " TERMINAL 1 " TO GROUND AND CAUSES THE WIPER MOTOR TO
RUN AT LOW SPEED.
5. WASHER CONTINUOUS OPERATION
WITH WASHER SW TURNED TO ON, THE CURRENT FLOWS FROM TERMINAL 2 OF THE WAHSER MOTOR " TERMINAL 1 "
TERMINAL 8 OF THE WIPER AND WASHER SW " TERMINAL 16 " TO GROUND AND CAUSES TO THE WASHER MOTOR TO RUN,
AND WINDOW WASHER IS JET. THIS CAUSES THE CURRENT TO FLOW WASHER CONTINUOUS OPERATION CIRCUIT IN TERMINAL
18 OF THE WIPER AND WASHER SW " TERMINAL 7 " TERMINAL 3 OF THE FRONT WIPER MOTOR " TERMINAL 1 " TO GROUND
AND FUNCTION.

WHEN THE IGNITION SW IS TURNED ON, CURRENT FLOWS TO TERMINAL 2 OF THE WASHER MOTOR, TERMINAL 1 OF THE REAR WIPER
MOTOR AND RELAY THROUGH THE WIPER FUSE.
1.REAR WIPER NORMAL OPERATIONWITH THE IGNITION SW TURNED ON AND THE REAR WIPER AND WASHER SW TURNED ON, THE CURRENT FLOWING TO TERMINAL 1 OF
THE REAR WIPER RELAY FLOWS TO TERMINAL 3 OF THE RELAY " TERMINAL 1 OF THE REAR WIPER AND WASHER SW " TERMINAL 16 "
TO GROUND. THUS, THE RELAY COIL IS ACTIVATED AND THE CURRENT TO TERMINAL 1 OF THE REALY FLOWS TO TERMINAL LM "
TERMINAL LM OF THE REAR WIPER MOTOR " MOTOR " TO GROUND AND CAUSES THE MOTOR TO OPERATE THE WIPER.
2.REAR WIPER INTERMITTENT OPERATIONWHEN THE IGNITION SW IS ON AND THE REAR WIPER AND WASHER SW IS TURNED TO INT POSITION, CURRENT FLOWING TO TERMINAL 1
OF THE REAR WIPER MOTOR AND RELAY FLOWS TO TERMINAL 2 OF THE RELAY " TERMINAL 10 OF THE REAR WIPER AND WASHER SW
" TERMINAL 16 " 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 CHANGING AND DISCHARGING OF THE CONDENSER INSTALLED
INSIDE THE RELAY.
3.WASHER OPERATIONWITH 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 WASHER MOTOR FLOWS TO TERMINAL 3 OF THE MOTOR " TERMINAL 2 OF
THE REAR WIPER AND WASHER SW " TERMINAL 16 " 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.
