System Outline

When the Ignition SW turned ON, current flows through the Gauge fuse to TERMINAL 1 of the power main 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 --> TERMINALS 7 and 8 of the power Window Master SW, TERMINALS 3 and 4 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 (Manual SW) in UP position. The current flowing to TERMINALS 7 and 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 --> TERMINALS 2 and 1 to GROUND and causes the Power Window Motor to rotate in the up direction. The Window Ascends only while the SW is being pulled. In down operation, the flow of current from TERMINALS 7 and 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 and 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 TERMINALS 7 and 8of 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 and 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 pulled, 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 and 1 increases. As a result, the solenoid stops operating, the auto SW turns OFF and flow from TERMINALS 7 and 8 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 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 GROUND,so the motor stops, causing auto down operation to stop. If the master SW is pulled continuously, the motor rotates in the up direction in manual up operation.

4. MANUAL OPERATION BY POWER WINDOW CONTROL SW (PASSENGER'S WINDOW)
With Power Window SW (Passenger's) pulled to the up side, current flowing from TERMINAL 4 of the power window control SW flows to TERMINAL 3 of the Power Window Control SW --> TERMINAL 2 of the Power Window Motor --> TERMINAL 1 --> TERMINAL 1 of the Power Window Control SW --> TERMINAL 2 --> TERMINAL 5 of the master SW --> TERMINALS 1 and 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 Control SW is pulled to the up side. When the window desends, 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 pulled 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 TERMINALS 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.
