With the ignition switch in the ON position, voltage is applied through the power window circuit breaker to the following switches:

The LH front power window/door lock switch is permanently grounded to G200.

When the LH front window switch is depressed, the DOWN/AUTO DOWN contacts close. This allows voltage to be applied to the LH front power door window motor. The LH front power window motor is grounded through the normally closed UP contacts of the LH front window switch to G200. With both power and ground supplied to the motor, the motor turns and opens the window. The motor stops when one of the following actions occur:

Lift the LH front window switch on order to close the window. This closes the UP contacts and allows voltage to be applied to the other side of the LH front power window motor. The LH front power window motor is normally grounded through the normally closed DOWN/AUTO DOWN contacts of the LH front window switch to G200. With both power and ground supplied to the motor, the motor turns and closes the window. The LH front power window motor stops when one of the following actions occurs:

The RH front, LH rear and RH rear windows can be operated by two separate switches:

Depressing the RH front, LH rear remote or RH rear remote power window switch closes the DOWN contacts. This allows voltage to be applied through the appropriate window switch (located on the door) to the window motor. The window motor is grounded through the appropriate window switch (located on the door) and the normally closed UP contacts of the depressed switch to G200. With both power and ground supplied to the motor, the motor turns and opens the window. The window motor stops whenever one of the following conditions occurs:

In order to close the RH front, LH rear, or RH rear window, lift the appropriate window switch (in the LH front power window/door lock switch or the center console). This closes the UP contacts and supplies voltage through the appropriate window switch (located on the door) to the window motor. In this case, the window motor grounds through the appropriate window switch and the normally grounded DOWN contacts of the lifted switch to G200. With both power and ground supplied to the motor, the motor turns and closes the window. The motor stops whenever one of the following conditions occurs:

The other method of operating the windows is through the window switch located on the appropriate door. When any one of these switches is depressed to the DOWN position, the following actions occur:

The window motor grounds to G200 through the following components:

With both power and ground supplied to the motor, the motor turns and opens the window. The motor stops when one of the following actions occurs:

Closing the window may be accomplished by lifting the appropriate window switch. This closes the UP contacts of that switch and applies voltage directly through the lifted switch to the appropriate motor. The window motor grounds through the lifted switch and through the normally grounded DOWN contacts in the other switch to G200. With both power and ground supplied to the motor the motor begins to turn and close the window. The motor stops whenever the following actions occur:

The LH front power window/door lock switch also contains circuitry for the AUTO DOWN and WINDOW LOCK features. the AUTO DOWN feature allows the LH front window to open automatically to the fully open position. When the LH front window switch is depressed to the AUTO DOWN position, the AUTO DOWN control circuitry holds the DOWN/AUTO DOWN contacts of the LH front power window/door lock switch closed. With these contacts closed, the LF front power window motor will operate in the same manner as described earlier. Once the window is completely open, the ECB and the control circuitry force the DOWN/AUTO DOWN contacts open, returning the contacts to their normally grounded state. The WINDOW LOCK feature allows the RH front, LH rear and RH rear windows to be locked out. When the window lock switch is depressed, only the LH front window switch in the LH front power window/door lock switch is operational.
