Windows: Description and Operation

GLASS, FRAMES AND MECHANISMS

Power Window Operation
The power window system operates under the control of the accessory delay relay. The instrument cluster module (ICM) will ground 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 switch located on each door panel. The driver window control switch has two modes of operation for the driver power window, manual and auto. All other windows operate in the manual mode only.

Manual mode will move 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 first 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 second detent position and then released. OTD is controlled internally by the driver window control switch.

The power window system will only operate if:
- The ignition is in the RUN or ACC position or
- 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 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.
