Power Window Motor: Description and Operation

With the Ignition SW turned ON, current flows through the GAUGE fuse to TERMINAL 3 of the Power Relay --> TERMINAL 1 --> GROUND. This activates the relay and the current from FL POWER fuse flows to TERMINAL 4 of the Power Relay --> TERMINAL 2 --> TERMINALS 7 and 8 of the power window master SW, to TERMINAL 5 of the power window SW front RH, rear LH and rear RH.

1. MANUAL UP OPERATION (DRIVER'S SIDE)
With the Ignition SW turned ON and with the power window master SW (Manual SW) at UP position, current flows to TERMINALS 7 and 8 of the Power Window Master SW --> TERMINAL 6 --> TERMINAL 3 of the Power Window Motor front LH --> TERMINAL 1 --> TERMINAL 13 of the Power Window Master SW --> TERMINALS 2 and 1 --> GROUND, causing the power window motor to rotate in the up direction. The window ascends only while the Power Window Master SW is being pulled.
In down operation, the current flow to TERMINALS 7 and 8 of the power window master SW flows to TERMINAL 13 --> TERMINAL 1 of the Power Window Motor front LH --> TERMINAL 3 --> TERMINAL 6 of the Power Window Master SW --> TERMINALS 2 and 1 --> GROUND. According to the flow, the motor rotates in the Down direction, lowering the window.

2. AUTO DOWN OPERATION (DRIVER'S SIDE)
With the ignition SW ON and with the auto down SW of the power window master SW in DOWN position, current flows to TERMINALS 7 and 8 of the Power Window Master SW --> TERMINAL 13 --> TERMINAL 1 of the Power Window Motor front LH --> TERMINAL 3 --> TERMINAL 6 of the Power Window Master SW --> TERMINALS 1 and 2 --> 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 between TERMINAL 6 of the power window master SW and TERMINALS 1 and 2 increases. As a result, the solenoid stops operating, auto down SW turns OFF, and the current from TERMINAL 7 and 8 of the power window 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 power window master SW and the current does not flow from TERMINAL 6 of the power window master SW --> to TERMINALS 1 and 2, so the motor stops, causing auto down operation to stop. If the manual SW is pushed continuously, the motor rotates in the up direction in manual up operation.

4. MANUAL OPERATION BY POWER WINDOW SW (PASSENGER'S SIDE)
With the power window SW front RH pulled to the up side, the current from TERMINAL 5 of the power window SW front RH flows to TERMINAL 1 of the power window SW --> TERMINAL 3 of the power window motor --> TERMINAL 1 --> TERMINAL 4 of the power window SW --> TERMINAL 3 --> TERMINAL 5 of the power window master SW --> TERMINALS 1 and 2 --> GROUND, causing the power window motor front RH to rotate in the up direction. Up operations continues only while the power window SW is being pulled to the up side. When the window descends, the current to the motor flows in the opposite direction, from TERMINAL 1 to TERMINAL 3, and the motor rotates in reverse.
When the window lock SW is pushed out to the normal side, the ground circuit to the front RH windows becomes open. As a result, even if open/close operation of the front RH 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 front RH window can not be operated and window lock occurs.
Furthermore rear LH, RH window operate the same as the above operation.

5. KEY OFF POWER WINDOW OPERATION
With the Ignition SW turned from ON to OFF, the door lock control relay operates and keeps the current flow from FL POWER fuse to TERMINAL 8 of the door lock control relay --> TERMINAL 15 --> TERMINAL 3 of the power relay --> TERMINAL 1 --> GROUND for about 60 seconds. The same as normal operation, the current flows from FL POWER fuse to TERMINAL 4 of the power relay --> TERMINAL 2 --> TERMINALS 7 and 8 of the power window master SW, to TERMINAL 5 of the power window SW front RH. As a result, for about 60 seconds after the ignition SW is turned OFF, it is possible to raise and lower the window by the functioning of this relay. Also, by opening the front door (the door courtesy SW ON) within about 60 seconds after turning the ignition SW to OFF, a signal is input to TERMINAL 2 or 14 or of the door lock control relay. As a result, the relay turns OFF, and up and down movement of the window stops.
