POWER WINDOW

WHEN THE IGNITION SW TURNED ON, CURRENT FLOWS THROUGH THE GAUGE FUSE 

 

TERMINAL 7 OF INTEGRATION RELAY  

 

TERMINAL  A  3  

 

TERMINAL 1 OF THE POWER RELAY 

 

TERMINAL 2 

 

TO GROUND.  THIS ACTIVATES THE RELAY AND

THE CURRENT FLOWING TO TERMINAL 5  OF THE RELAY FROM POWER FUSE FLOWS TO TERMINAL 3 OF THE RELAY 



TERMINAL 7 OF THE POWER WINDOW MASTER SW, TERMINAL 5  OF THE POWER WINDOW CONTROL SW.

1. MANUAL OPERATION (DRIVER’S WINDOW)

WITH THE IGNITION SW TURNED ON AND WITH THE POWER WINDOW MASTER SW (FRONT LH) IN UP POSITION, THE CURRENT
FLOWING TO TERMINAL 7 OF THE POWER WINDOW MASTER SW FLOWS TO TERMINAL 6 OF THE MASTER SW 

 

TERMINAL 1 OF

THE POWER WINDOW MOTOR 

 

TERMINAL 2 

 

TERMINAL 13 OF THE MASTER SW 

 

TERMINAL 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 OF THE POWER WINDOW MASTER SW

TO TERMINAL 13 OF THE MASTER SW CAUSES THE FLOW OF CURRENT FROM TERMINAL 2 OF THE MOTOR 

 

TERMINAL 1 



TERMINAL 6 OF THE MASTER SW 

 

TERMINAL 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

WHEN THE FRONT LH WINDOW CONTROL SW IN THE POWER WINDOW MASTER SW IS PUSHED STRONGLY ON THE DOWN
SIDE, CURRENT FLOWS FROM TERMINAL 7 OF THE MASTER SW 

 

TERMINAL 13 

 

TERMINAL 2 OF THE POWER WINDOW

MOTOR 

 

TERMINAL 1 

 

TERMINAL 6 OF THE MASTER SW 

 

TERMINAL 1 

 

TO GROUND. BECAUSE THE HOLD CIRCUIT

INSIDE THE MASTER SW KEEPS THE RELAY ON THE DOWN SIDE ACTIVATED, THE POWER WINDOW MOTOR CONTINUES
OPERATING EVEN IF THE POWER WINDOW MASTER SW IS RELEASED. WHEN THE DRIVER’S WINDOW IS FULLY LOWERED,
THE HOLD CIRUCIT TURNS OFF AND THE RELAY ON THE DOWN SIDE TURNS OFF, SO AUTO DOWN OPERATION STOPS.

3. STOPPING OFAUTO DOWN AT DRIVER’S WINDOW

WHEN THE MANUAL SW (FRONT LH) IS PULLED 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 TERMINAL 1, SO

THE MOTOR STOPS, CAUSING AUTO DOWN OPERATION TO STOP. IF THE MASTER SW IS PULLED CONTINUOUS, THE MOTOR
ROTATES IN THE UP DIRECTION IN MANUAL UP OPERATION.

4. MANUAL OPERATION BY POWER WINDOW SW (FRONT RH WINDOW)

WITH THE POWER WINDOW CONTROL SW (FRONT RH) PULLED TO THE UP SIDE, CURRENT FLOWING FROM TERMINAL 5  OF
THE POWER WINDOW CONTROL SW FLOWS TO TERMINAL 2 OF THE POWER WINDOW CONTROL SW 

 

TERMINAL 2 OF THE

POWER WINDOW MOTOR 

 

TERMINAL 1 

 

TERMINAL 3 OF THE POWER WINDOW CONTROL SW  

 

TERMINAL 1 



TERMINAL 5 OF THE MASTER SW

   

TERMINAL 1 

 

TO GROUND AND CAUSES THE POWER WINDOW MOTOR (FRONT RH) TO

ROTATE IN THE UP DIRECTION. UP OPERATION CONTINUES ONLY WHILE THE POWER WINDOW CONTROL SW IS PULLED TO
THE UP SIDE. WHEN THE WINDOW DESCENDS, THE CURRENT FLOWING TO THE MOTOR FLOWS IN THE OPPOSITE
DIRECTION, FROM TERMINAL 2 TO TERMINAL 1, 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 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.

5. KEY OFF POWER WINDOW OPERATION

WITH THE IGNITION SW TURNED FROM ON TO OFF, INTEGRATION RELAY OPERATES AND CURRENT FLOWS FROM DOOR
FUSE TO TERMINAL  A  13 OF THE RELAY  

 

TERMINAL  A  3 

 

TERMINAL 1 OF POWER RELAY 

 

TERMINAL 2 

 

TO GROUND

FOR ABOUT 43 SECONDS. THE SAME AS NORMAL OPERATION, THE CURRENT FLOWS FROM POWER FUSE 

 

TERMINAL 5 OF

THE POWER RELAY 

 

TERMINAL 3 

 

TERMINAL 7  OF THE POWER WINDOW MASTER SW AND TERMINAL 3 OF THE POWER

RELAY 

 

TO  TERMINAL 5 OF THE POWER WINDOW CONTROL SW.  AS A  RESULT, FOR ABOUT 43 SECONDS AFTER THE

IGNITION SW IS TURNED OFF, THE FUNCTIONING OF THIS RELAY MAKES IT POSSIBLE TO RAISE AND LOWER THE POWER
WINDOW. ALSO, BY OPENING THE FRONT DOOR (DOOR OPEN DETECTION SW ON) WITHIN ABOUT 43 SECONDS AFTER
TURNING THE IGNITION SW TO OFF, A SIGNAL IS INPUT TO TERMINALS  A  6 OR 6 OF INTEGRATION RELAY. AS A RESULT, THE
RELAY TURNS OFF AND UP AND DOWN MOVEMENT OF THE POWER WINDOW STOPS.
