Power Window Motor: Description and Operation

Current always flows TERMINAL 2 of the Power Main Relay through the POWER fuse. With the Ignition SW turned ON. Current flows through the GAUGE fuse to TERMINAL 1 of the Power Main Relay --> TERMINAL 3 --> GROUND. This activates the Power Main Relay, and current flowing to TERMINAL 4 of the Power Main Relay flows to TERMINAL 9 of the Power Window Master SW and TERMINAL 5 of the Power Window Control SW RH.

1. MANUAL OPERATION (DRIVER'S WINDOW)
With the Ignition SW turned ON and the Power Window Master SW in UP position, the current flowing to TERMINAL 9 of the Power Window Master SW flows to TERMINAL 3 --> TERMINAL 1 of the Power Window Motor LH --> Motor --> TERMINAL 2 --> TERMINAL 4 of the Power Window Master SW --> TERMINAL 6 --> GROUND and causes the Power Window Motor LH to rotate in the up direction. The window ascends only while the SW is being pulled. In down operation, The flow of current from TERMINAL 9 of the Power Window Master SW flows to TERMINAL 4 --> TERMINAL 2 of the Power Window Motor LH --> Motor --> TERMINAL 1 --> TERMINAL 3 of the Power Window Master SW --> TERMINAL 6 --> GROUND, causing the motor to rotate in reverse, lowering the window.

2. AUTO DOWN OPERATION (DRIVER'S WINDOW)
With the Ignition SW ON and with the Driver's SW of the Power Window Master SW in DOWN position, current flowing to TERMINAL 9 of the Power Window Master SW flows to TERMINAL 4 --> TERMINAL 2 of the Power Window Motor LH --> Motor --> TERMINAL 1 --> TERMINAL 3 of the Power Window Master SW --> TERMINAL 6 --> GROUND. causing the Power Window Motor LH to rotate towards the down side. Then the solenoid in the Power Window Master SW is activated and it locks the Driver's SW being pushed. causing the Power Window Motor LH to continue to rotate in auto down operation.

When the window has completely descended, the current flow between TERMINAL 3 of the Power Window Master SW and TERMINAL 6 increases. As a result, the solenoid stops operating, the Driver's SW turns OFF and flow from TERMINAL 9 of the Power Window Master SW to TERMINAL 4 is cut OFF, stopping the motor so that auto stop occurs.

3. STOPPING OF AUTO DOWN AT DRIVER'S WINDOW
When the Power Window Master SW is pulled to the up side during auto down operation, a GROUND circuit opens in the Power Window Master SW and current does not flow from TERMINAL 3 of the Power Window Master SW --> TERMINAL 6, so the Power Window Motor LH stops rotating, causing auto down operation to stop. If the master SW is pulled continuously, the Power Window Motor rotates in the up direction in manual up operation.

4. MANUAL OPERATION BY POWER WINDOW CONTROL SW RH
With the Power Window Control SW RH pushed to the up side, current through TERMINAL 5 of the Power Window Control SW RH flows to --> TERMINAL 1 --> TERMINAL 2 of the Power Window Motor RH --> TERMINAL 1 --> TERMINAL 4 of the Power Window Control SW RH --> TERMINAL 3 --> TERMINAL 7 of the Power Window Master SW --> TERMINAL 6 --> GROUND, and causes the Power Window Motor RH to rotate in the up direction. Up operation continues only while Power Window Control SW RH is pushed 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 Front Passenger's Window becomes open. As a result, even if open/close operation of the Front Passenger's Window is tried, the current from TERMINAL 6 of the Power Window Master SW is not grounded and the motor does rotate, so the front Passenger's Window can not be operated and the window locks.
