Power Window Operation
The power window system operates under the control of the accessory delay relay. The instrument cluster module (ICM) grounds the relay coil to provide power to the power window system.

Power Window Control
The power window system can be operated from the driver window control switch or from the window control switches located on each door panel. The driver window control switch has 2 modes of operation for the driver power window, manual and auto. All other windows operate in the manual mode only.

Manual mode moves the window downward until the switch is released. The driver power window will operate in the manual mode when the driver window control switch is pressed to the 1st detent position.

Auto mode provides the one-touch down (OTD) feature for the driver front power window. The OTD function allows the driver front power window to be completely lowered when the driver window control switch is pressed to the 2nd detent position and then released. OTD is controlled by the driver window control switch.

The power window system will only operate if:
- the ignition is in the RUN or ACC position.
- the accessory delay feature is in the active mode.

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 activates the heated grid relay. When the heated grid relay is active, both the rear window defrost grid and the heated mirror elements are energized.

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