Power Window Motor: Description and Operation

When the ignition SW is turned ON, current plows through the GAUGE fuse TERMINAL 1 of door lock control relay --> TERMINAL 15 --> TERMINAL 1 of the power main relay --> TERMINAL 2 --> GROUND. This activates the relay, and the current from power fuse flows through TERMINAL 5 of the relay to TERMINAL 3 of the relay --> TERMINAL 9 (C/P), 7 or 8 (except C/P) of the power window master SW --> TERMINAL 6 (C/P), 1 or 2 (except C/P) of the master SW --> GROUND.

1. MANUAL OPERATION (DRIVER'S WINDOW)
With the ignition SW turned ON and the power window master SW (manual SW) at UP position, the current through TERMINAL 9 (C/P), 7 or 8 (except C/P) of the power window master SW flows to TERMINAL 3 (C/P), 6 (except C/P) of the master SW --> TERMINAL 1 (C/P), 2 (except C/P) of the power window motor --> TERMINAL 2 (C/P), 1 (except C/P) --> TERMINAL 4 (C/P), 13 (except C/P) of the master SW --> TERMINAL 6 (C/P), 1 or 2 (except C/P) --> GROUND, rotating the power window motor in the up direction. The window ascends only while the power window master SW (manual SW) is pushed. In down operation, the current through TERMINAL 9 (C/P), 7 or 8 (except C/P) of the power window master SW flows to TERMINAL 4 (C/P), 13 (except C/P) of the master SW --> TERMINAL 2 (C/P), 1 (except C/P) of the power window motor --> TERMINAL 1 (C/P) 2 (except C/P) --> TERMINAL 3 (C/P), 6 (except C/P) TERMINAL 6 (C/P), 1 or 2 (except C/P) --> GROUND, rotating the motor in the down direction.

2. AUTO DOWN OPERATION
With the ignition SW ON and the auto SW of the power window master SW in down position, the current through TERMINAL 9 (C/P), 7 or 8 (except C/P) of the master SW flows to TERMINAL 4 (C/P), 13 (except C/P) of the master SW --> TERMINAL 2 (C/P), 1 (except C/P) of the power window motor --> TERMINAL 1 (C/P), 2 (except C/P) --> TERMINAL 3 (C/P), 6 (except C/P) of the master SW --> TERMINAL 6 (C/P), 1 or 2 (except C/P) --> GROUND, causing the motor to rotate in down direction. Then the solenoid in the master SW is activated and it locks the auto SW being pushed, keeping the motor ON rotating in auto down operation. When the window has completely descended, the current between TERMINAL 3 (C/P), 6 (except C/P) of the master SW and TERMINAL 6 (C/P), 1 or 2 (except C/P) of the master SW increases. As a result, the solenoid stops operating, the auto SW is turned OFF, and the current from TERMINAL 9 (C/P), 7 or 8 (except C/P) of the master SW to TERMINAL 4 (C/P), 13 (except C/P) 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 the current from TERMINAL 3 (C/P), 6 (except C/P) of the master SW to GROUND is cut OFF, 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)
When power window control SW (passenger's) is pushed to the up side, the current through TERMINAL 5 of the power window control SW flows to TERMINAL 1 of the SW --> TERMINAL 2 of the power window motor --> TERMINAL 1 --> TERMINAL 4 of the power window control SW --> TERMINAL 3 --> TERMINAL 7 (C/P), 5 (except C/P) of the master SW --> TERMINAL 6 (C/P), 1 or 2 (except C/P) --> GROUND, causing 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 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 6 (C/P), 1 or 2 (except C/P) 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 operates the sane as the above circuit.

5. KEY OFF POWER WINDOW OPERATION
With ignition SW turned from ON to OFF, the door lock control relay operates and current flows from power fuse to TERMINAL 8 of the relay --> TERMINAL 15 --> TERMINAL 1 of power main relay --> TERMINAL 2 --> GROUND for about 60 seconds. The same as normal operation, the current flows from power fuse --> TERMINAL 5 of the power main relay --> TERMINAL 3 --> TERMINALS 9 (C/P), 7 or 8 (except C/P) of the power window master SW and through TERMINAL 3 of the power main relay to TERMINAL 5 of the power window control SW. As a result, for about 60 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 60 seconds after turning the ignition SW to OFF, a signal is input to door lock control relay. As a result, the relay turns OFF, and up and down movement of the power window stops.
