Windows and Glass: Description and Operation

GLASS, FRAMES AND MECHANISMS

The glass, frames and mechanisms consist of the:
- window control switches.
- window regulators.
- window regulator motors.
- door glass.
- door glass top runs.
- rear quarter glass.
- heated rear window.
- rear window defrost switch.
- rear window defrost relay.
- driver's door module (DDM)

The rear door glass top run contains the quarter glass and is removed as an assembly.

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 manual mode only.

Manual mode moves the window downward until the switch is released. 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 momentarily 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.

The heated rear window is controlled by the DDM. The ignition switch must be in RUN for the heated rear window to operate. When the rear window defrost switch is pressed, the DDM activates the rear window defrost relay which supplies voltage to the antenna module and the heated rear window grid.
