Windows: Description and Operation

Current always through the Power fuse flows to TERMINAL 5 of the power main relay. With 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 current flows from TERMINAL 3 of the power main relay --> TERMINAL 7 of the Power Window master SW, to TERMINAL 4 of the Power Window Control SW (Passenger's Side) and to TERMINAL 4 of the quarter Power Window SW LH, RH (Convertible).

1. MANUAL Operation BY POWER WINDOW SW (DRIVER'S WINDOW)
With the Ignition SW turned ON and with the Power Window master SW in UP position, current to TERMINAL 7 of the Power Window master SW flows to TERMINAL 8 of the master SW --> TERMINAL 1 of the Power Window motor (Driver's) --> Motor --> TERMINAL 2 --> TERMINAL 6 of the master SW --> TERMINAL 9 --> Ground, causing 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 6 of the master SW causes the flow of current from TERMINAL 2 of the motor --> Motor --> TERMINAL 1 --> TERMINAL 8 of the master SW --> TERMINAL 9 --> Ground, flowing in the opposite direction to manual up operation, causing the motor to rotate in reverse and lowering the Window.

2. AUTO DOWN OPERATION
With the Ignition SW ON and the driver's SW of the Power Window master SW in Down position, current to TERMINAL 7 of the master SW flows to TERMINAL 6 of the master SW --> TERMINAL 2 of the Power Window motor --> Motor --> TERMINAL 1 --> TERMINAL 8 of the master SW --> TERMINAL 9 --> Ground, causing the motor to rotate towards the down side. Then the solenoid in the master SW is activated and it locks the Driver's SW being pushed, causing the motor to continue to rotate in auto down operation.
When the Window has completely descended, the current flowing between TERMINAL 8 of the master SW and TERMINAL 9 increases. As a result, the solenoid stops operating, the driver's SW turns OFFand the flow from TERMINAL 7 of the master SW to TERMINAL 6 is cut OFF, stopping the motor so that auto stop occurs

3. STOPPING OF AUTO DOWN AT DRIVER'S WINDOW
When the driver's SW 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 8 of the master SW to TERMINAL 9, so the motor stops, causing auto down operation to stop. If the driver's 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 Control SW (Passenger's Side) pushed to the up side, current from TERMINAL 4 of the Power Window Control SW flows to TERMINAL 1 of the Power Window Control SW --> TERMINAL 2 of the Window Motor --> Motor -->TERMINAL 1 --> TERMINAL 3 of the Power Window Control SW --> TERMINAL 5 --> TERMINAL 4 of the Power Window master SW --> Window lock SW --> TERMINAL 9 --> Ground, causing the Power Window Motor (Passenger's Side) to rotate in the up direction. Up operation continues only while the Power Window SW is pushed to the up side. When the Window descends, current to the motor flows in the opposite direction, from TERMINAL 1 to Motor --> TERMINAL 2and the motor rotates in reverse. When the Window lock SW is pushed out to the normal side, the Ground circuit id the Passenger's Window becomes open.
As a result, even if Open/Close operation of the passengers Window is tried, current from TERMINAL 7 of the Power Window Master SW is not grounded and the motor does not rotate, so the Passenger's Window cannot be operated and Window lock occurs.

5. KEY OFF POWER WINDOW OPERATION
With the Ignition SW turned from ON to OFF, the Door lock ECU operates and current flows from the Door fuse to TERMINAL 8 of the Door Lock Control Relay --> TERMINAL 15 --> TERMINAL 1 of the power main relay TERMINAL 2 --> Ground for about 60 Seconds. The same as normal operation, current flows from the power fuse to TERMINAL 5 of the power main relay --> TERMINAL 3 -> TERMINAL 7 of the Power Window master SW and TERMINAL 4 of Power Window Control SW (Passenger's Side). As a result, for about 60 Seconds after the Ignition SW is turned OFF, it is possible to raise and lower the Power Window by the functioning of this relay. Also, by opening the Door (Door Courtesy SW ON) within about 60 Seconds after turning the Ignition SW to OFF. A signal is input to TERMINAL 2, 14 of Door Lock Control Relay. As a result the ECU turns OFF, and Up and Down of the movement of the Window stops.

6. MANUAL OPERATION BY QUARTER WINDOW SW (CONVERTIBLE)
With the quartet Power Window SW pushed to up side, current from TERMINAL 4 of he quarter Power Window SW LH, RH flows to TERMINAL 2 (LH), 3 (RH) --> TERMINAL 2 of the quarter Power Window Motor--> Motor --> TERMINAL 1 of the Motor --> TERMINAL 1 (LH), 6 (RH) of the quarter Power Window SW --> TERMINAL 3 (LH), 1 (RH) --> TERMINAL 3 of the Power Window master SW --> Window lock SW --> TERMINAL 9 --> Ground, causing the quarter Power Window motor to rotate in the up direction. Up operation continuous only while the quarter Power Window SW is pushed to up side, when the Window descends, the current flow to the motor flows in the opposite direction, from TERMINAL 1 of the Motor -->Motor --> TERMINAL 2, and the motor rotates in reverse
When the Window lock SW is pushed out to the normal side, the Ground circuit to the quarter Power Window becomes open. As a result, even if open/close operation of quarter Window is tried, current from TERMINAL 3 (LH), 1 (RH) of the quarter Power Window SW is not grounded and the motor does not rotate. so the quarter Power Window can not be operated ant Window lock occurs.
