Description & Operation

With the Ignition Switch in "ON" or "START," voltage is applied through the GAUGE Fuse, Audio Alarm Module and Junction Block 3 to the coil of the Accessory Power Relay. Voltage is applied at all times through the Accessory Fusible Link to the switching portion of the Accessory Power Relay.

The Accessory Power Relay is permanently grounded through Junction Connector 1 to G200. WIRING DIAGRAMS  . When the coil of the Accessory Power Relay is energized, the relay contacts close and voltage is applied to the Left Front Power Window/Door Lock Switch, Right Front Power Window Switch, Left Rear Power Window Switch and Right Rear Power Window Switch. The Left Front Power Window/Door Lock Switch is permanently grounded through Junction Connector 1 to G200.

When the Left Front Window Switch is depressed, the DOWN/AUTO DOWN contacts close, thus allowing voltage to be applied to the Left Front Power Window Motor. The Left Front Power Window Motor is grounded through the normally grounded UP contacts of the Left Front Power Window/Door Lock Switch to G200. With both power and ground supplied to the motor, it begins to turn and open the window. The Left Front Power Window Motor will stop once the window is completely open, via an electronic circuit breaker (ECB) within the motor, or whenever the Left Front Window Switch is released. By releasing the switch, the DOWN/AUTO DOWN contacts return to their normally grounded position.

Closing the Left Front Window is accomplished by pulling up on the switch, the UP contacts close, thus allowing voltage to be applied to the other side of the Left Front Power Window Motor. In this case, the Left Front Power Window Motor grounds through the normally grounded DOWN/AUTO DOWN contacts of the Left Front Power Window/Door Lock Switch to G200. With power and ground supplied to the motor, it begins to turn and closes the window. The Left Front Power Window Motor will stop once the window is completely closed, via the Electronic Circuit Breaker (ECB), or whenever the Left Window Switch is released. Once the switch is release, the UP contacts return to their normally grounded position.

The Right Front, Left Rear and Right Rear Windows can be operated by two separate switched. One being in the Left Front Power Window/Door Lock Switch and the other being the individual switches located on each door. When either the Right Front, Left Rear or Right Rear Window Switch in the Left Front Power Window/Door Lock Switch is depressed, its DOWN contacts close, thus allowing voltage to be applied through the contacts of the appropriate Window Switch (located on the door) to the Window Motor. The Window Motor is grounded through that particular Window Switch (located on the door) and the normally grounded UP contacts of the Left Front Power Window/Door Lock Switch to G200. With both power and ground supplied to the motor, it begins to turn and open the window. The Window Motor will stop once the window is completely open, via an EBC within the motor, or whenever the Window Switch is released. By releasing the switch, the DOWN contacts return to their normally grounded position.

Closing the Right Front, Left Rear or Right Rear Window is accomplished by pulling up on the appropriate Window Switch in the Left Front Power Window/Door Lock Switch. By pulling up on the switch, the UP contacts close, thus allowing voltage to be applied through the appropriate Window Switch (located on the door) to the appropriate Window Motor. In this case, the Window Motor grounds through that particular Window Switch and the normally grounded DOWN contacts of the Left Front Power Window/Door Lock Switch to G200.

With both power and ground supplied to the motor, it begins to turn and closes the window. The Window Motor will stop once the window is completely closed, via Electronic Circuit Breaker (ECB), or whenever the Window Switch is released. Once the switch is released, the UP contacts return to their normally grounded position.

The other method of operating the windows is through the Window Switches located on the Right Front, Left Rear and Right Rear Doors. When any one of these switches are depressed to the DOWN position, the DOWN contacts of that switch close, and voltage is applied directly through that switch to the appropriate Window Motor. The Window Motor grounds through the switch that was depressed and also through the normally grounded UP contacts of the Left Front Power Window/Door Lock Switch to G200. With both power and ground supplied to the motor, it begins to turn and open the window. The motor will stop when the window is completely open, via the Electronic Circuit Breaker (ECB), or whenever the Window Switch is released. By releasing the switch, the DOWN contacts return to their normally grounded position.

By pulling up on the Right Front Power Window Switch, or by depressing either of the Rear Window Switches to the UP position, the UP contacts of that switch close. This allows voltage to be applied directly through the appropriate switch contacts to the other side of the Window Motor. In this case the Window Motor grounds through that particular switch and through the normally grounded DOWN contacts of the Left Front Power Window/Door Lock Switch to G200. With both power and ground supplied to the motor, it begins to turn and closes the window. The Window Motor will stop once the window is completely closed, via the ECB, or whenever the Window Switch is released. Once the switch is released, the UP contacts return to their normally grounded position.

The Left Front Power Window/Door Lock Switch also contains circuitry for the AUTO DOWN and WINDOW LOCK features. The AUTO DOWN feature allows the Left Front Window to open automatically to the fully open position. When the Left Front Window Switch is depressed to the AUTO DOWN position, the Auto Down Control circuitry pulls and holds the DOWN/AUTO DOWN contacts of the Left Front Window Switch closed. With these contacts closed, the Left Front Window Motor will operate in the same manner as described earlier. When the window is completely open, the ECB and the control circuitry force the DOWN contacts to open, thus stopping the Window Motor. The WINDOW LOCK feature allows the Right Front Left Rear and Right Rear windows to be locked out. When the Window Lock Switch is depressed, only the Left Front Window is operational via the Left Front Power Window/Door Lock Switch.
