POWER WINDOW
WITH THE IGNITION SW TURNED ON, CURRENT FLOWS THROUGH THE GAUGE FUSE TO TERMINAL 1 OF THE POWER MAIN RELAY TERMINAL 3
TO GROUND. THIS ACTIVATES THE RELAY AND THE CURRENT FLOWING TO TERMINAL 2 OF THE RELAY FROM POWER CB FLOWS TO TERMINAL 4 OF
THE RELAY TERMINAL 7 OR 8 OF THE POWER WINDOW MASTER SW TO TERMINAL 5 (PASSENGER’S) AND TERMINAL 3 (REAR LH, RH) OF THE
POWER WINDOW SW.
1. MANUAL UP OPERATION (DRIVER’S WINDOW)
WITH THE IGNITION SW TURNED ON AND WITH THE POWER WINDOW MASTER SW (MANUAL SW) IN UP POSITION, THE CURRENT FLOWING TO
TERMINAL 7 OR 8 OF THE POWER WINDOW MASTER SW FLOWS TO TERMINAL 6 OF THE MASTER SW TERMINAL 2 OF THE POWER WINDOW
MOTOR TERMINAL 1 TERMINAL 13 OF THE MASTER SW TERMINAL 2 OR 1 TO GROUND AND CAUSES THE POWER WINDOW MOTOR TO
ROTATE IN THE UP DIRECTION. THE WINDOW ASCENDS ONLY WHILE THE SW IS BEING PUSHED. IN DOWN OPERATION, THE FLOW OF CURRENT
FROM TERMINAL 7 OR 8 OF THE POWER WINDOW MASTER SW TO TERMINAL 13 OF THE MASTER SW CAUSES THE FLOW OF CURRENT FROM
TERMINAL 1 OF THE MOTOR TERMINAL 2 TERMINAL 6 OF THE MASTER SW TERMINALS 2 OR 1 TO GROUND, FLOWING IN THE OPPOSITE
DIRECTION TO MANUAL UP OPERATION AND CAUSING THE MOTOR TO ROTATE IN REVERSE, LOWERING THE WINDOW.
2. AUTO DOWN OPERATION
WITH THE IGNITION SW ON AND WITH THE AUTO SW OF THE POWER WINDOW MASTER SW IN DOWN POSITION, CURRENT FLOWING TO
TERMINAL 7 OR 8 OF THE MASTER SW FLOWS TO TERMINAL 13 OF THE MASTER SW TERMINAL 1 OF THE POWER WINDOW MOTOR
TERMINAL 2 TERMINAL 6 OF THE MASTER SW TERMINAL 2 TO GROUND, CAUSING THE MOTOR TO ROTATE TOWARDS THE DOWN SIDE.
THEN THE SOLENOID IN THE MASTER SW IS ACTIVATED AND IT LOCKS THE AUTO SW BEING PUSHED, CAUSING THE MOTOR TO CONTINUE TO
ROTATE IN AUTO DOWN OPERATION. WHEN THE WINDOW HAS COMPLETELY DESCENDED, THE CURRENT FLOW BETWEEN TERMINAL 6 OF THE
MASTER SW AND TERMINAL 2 INCREASES. AS A RESULT, THE SOLENOID STOPS OPERATING, THE AUTO SW TURNS OFF AND FLOW FROM
TERMINAL 7 OF THE MASTER SW TO TERMINAL 13 IS CUT OFF, STOPPING THE MOTOR SO THAT AUTO STOP OCCURS.
3. STOPPING OF AUTO DOWN AT DRIVER’S WINDOW
WHEN THE MANUAL SW (DRIVER’S) IS PUSHED TO THE UP SIDE DURING AUTO DOWN OPERATION, A GROUND CIRCUIT OPENS IN THE MASTER SW
AND CURRENT DOES NOT FLOW FROM TERMINAL 6 OF THE MASTER SW TO GROUND SO THE MOTOR STOPS, CAUSING AUTO DOWN OPERATION
TO STOP. IF THE MASTER SW IS PUSHED CONTINUOUSLY, THE MOTOR ROTATES IN THE UP DIRECTION IN MANUAL UP OPERATION.
4. MANUAL OPERATION BY POWER WINDOW SW (PASSENGER’S WINDOW)
WITH POWER WINDOW SW (PASSENGER’S) PULLED TO THE UP SIDE, CURRENT FLOWING FROM TERMINAL 5 OF THE POWER WINDOW SW FLOWS
TO TERMINAL 1 OF THE POWER WINDOW SW TERMINAL 2 OF THE POWER WINDOW MOTOR TERMINAL 1 TERMINAL 4 OF THE POWER
WINDOW SW TERMINAL 3 TERMINAL 5 OF THE MASTER SW TERMINALS 1 OR 2 TO GROUND AND CAUSES THE POWER WINDOW MOTOR
(PASSENGER’S) TO ROTATE IN THE UP DIRECTION. UP OPERATION CONTINUES ONLY WHILE THE POWER WINDOW SW IS PULLED TO THE UP SIDE.
WHEN THE WINDOW DESCENDS, THE CURRENT FLOWING TO THE MOTOR FLOWS IN THE OPPOSITE DIRECTION, FROM TERMINAL 1 TO TERMINAL 2,
AND THE MOTOR ROTATES IN REVERSE. WHEN THE WINDOW LOCK SW IS PUSHED TO THE LOCK SIDE, THE GROUND CIRCUIT TO THE
PASSENGER’S WINDOW BECOMES OPEN. AS A RESULT, EVEN IF OPEN/CLOSE OPERATION OF THE PASSENGER’S WINDOW IS TRIED, THE CURRENT
FROM TERMINAL 1 AND 2 OF THE POWER WINDOW MASTER SW IS NOT GROUNDED AND THE MOTOR DOES NOT ROTATE, SO THE PASSENGER’S
WINDOW CAN NOT BE OPERATED AND WINDOW LOCK OCCURS. FURTHERMORE REAR LH RH WINDOW OPERATE THE SAME AS THE ABOVE CIRCUIT.
