TERMINAL 2 OF THE WASHER MOTOR AND TERMINAL 6 OF THE FRONT WIPER MOTOR FROM THE WIPER FUSE.
1. LOW SPEED POSITION
WITH THE WIPER SW TURNED TO LOW POSITION, THE CURRENT FLOWS FROM TERMINAL 18 OF THE FRONT WIPER AND
WASHER SW TO TERMINAL 7 " TERMINAL 3 OF THE FRONT WIPER MOTOR " TERMINAL 1 " 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 FROM TERMINAL 18 OF THE FRONT 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 THE WIPER SW TURNED TO INT POSITION, THE RELAY OPERATES AND THE CURRENT WHICH IS CONNECTED BY RELAY
FUNCTION FLOWS FROM THE TERMINAL 18 OF THE FRONT WIPER AND WASHER SW" TERMINAL 16" TO GROUND. THIS
FLOWS OF THE CURRENT OPERATES THE INTERMITTENT CIRCUIT AND THE CURRENT FLOWS FROM TERMINAL 18 OF THE
FRONT 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 THE WIPER SW TURNED TO MIST POSITION, THE CURRENT FLOWS FROM TERMINAL 18 OF THE FRONT 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 THE WASHER SW TURNED TO ON, THE CURRENT FLOWS THROUGH TERMINAL 2 OF THE WASHER MOTOR "TERMINAL
1" TERMINAL 8 OF THE FRONT 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 FRONT WIPER AND WASHER SW " TERMINAL 7 " TERMINAL 3 OF THE FRONT WIPER MOTOR" TERMINAL
