Windows and Glass: Description and Operation

Glass, Frames and Mechanisms

The glass, frames and mechanisms consist of the following components:

- Accessory delay relay
- Antenna module
- Central Junction Box (CJB)
- Door window glass
- Door glass top runs
- HVAC module
- Lighting Control Module (LCM)
- Rear quarter window glass and glass top run assembly
- Rear window defrost relay
- Rear window defrost switch
- Rear window glass
- Window control switches
- Window regulators
- Window regulator motors
- Windshield glass

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 one-touch down. All other windows operate in manual mode only.

Manual mode moves the window downward until the switch is released. The one-touch down function allows the driver front power window to be completely lowered when the driver window control switch is pressed momentarily and then released.

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