PRINCIPLES OF OPERATION

The left front window switch may be used to raise or lower all windows, or the individual side window from the individual door window control switch.

The instrument control module (ICM) controls power to the power window system by activating or deactivating the delayed accessory relay.

The one-touch down feature will completely lower the driver side window when the master control is fully depressed and then released. The one-touch down feature is integrated into the LF window control switch.

There are two modes of LF window down operation: manual mode and auto mode. The manual mode is selected by pressing the LF window control switch to the first (down) position. In manual mode, the window will move downward only while the switch is depressed. When the LF window control switch is pressed to the second down position, it enters auto mode and the window will open completely with a momentary press of the switch.

When the one-touch down feature has been activated, it will stay on until one of the following conditions is met:
- The LF window control switch is pushed to the UP position.
- The LF window control switch is released (OFF position) and then moved to the down position (first detent) or one-touch down (OTD) position second detent).
- Seven seconds have elapsed since the OTD was initiated.

UP or DOWN window operation is enabled whenever the delayed accessory is active and the LF window control switch is pressed to the UP or DOWN position. The switch provides delayed accessory power to one side of the motor and ground to the other side. The one-touch down feature is not active when the LF window control switch is in the UP position.

Passenger windows may be raised or lowered using the LF window control switch or the appropriate passenger window control switch. Passenger window control switches receive power when the delayed accessory relay is active and the LF remote lock-out switch is in the UNLOCK position. When in the LOCK-OUT position, the passenger windows are deactivated.

The delayed accessory relay provides power for the operation of the power windows and the power roof opening panel. The delayed accessory relay is active whenever the ignition switch is in the RUN or the ACC position, or when the ignition switch is changed from RUN or ACC to the OFF/LOCK position and the LF and RF doors are closed.

The ICM will deactivate the delayed accessory feature when:
- the LF door is ajar and the ignition switch is in the OFF/LOCK or KEY-OUT position.
- the RF door is ajar and the ignition switch is in the OFF/LOCK or KEY-OUT position.
- 10 minutes have elapsed since the ignition switch was changed from ACC or RUN to the OFF/LOCK position.

Rear Window Defrost
The instrument cluster module (ICM) controls the rear window defrost grid and heated mirrors by controlling the state of the rear window defrost/mirror relay. When the rear window defrost switch is pressed, the ICM will activate the heated grid relay. When the heated grid relay is active, both the rear window defrost grid and heated mirror elements will be energized.

The ICM will deactivate the heated grid relay when one of the following conditions is met:
- The rear window defrost switch is pressed when the feature is active.
- Ignition switch state is changed from RUN to OFF/LOCK.
- The 10-minute timing function is completed.

Rear Sliding Window
OPEN or CLOSED window operation is enabled whenever the delayed accessory is active and the rear sliding window control switch is pressed to the OPEN or CLOSED position. The switch provides delayed accessory power to one side of the motor and ground to the other side.

The ICM will deactivate the delayed accessory feature when:
- the LF door is ajar and the ignition switch is in the OFF/LOCK or KEY-OUT position.
- the RF door is ajar and the ignition switch is in the OFF/LOCK or KEY-OUT position.
- 10 minutes have elapsed since the ignition switch was changed from ACC or RUN to the OFF/LOCK position.
