Windows and Glass: Description and Operation

Glass, Frames and Mechanisms

The glass, frames and mechanisms consist of the following:

- Accessory delay relay

- Door window regulator motors

- Front Controls Interface Module (FCIM)

- Front door glass top run

- Front door window glass

- HVAC module

- Liftgate window glass

- Rear door glass top run

- Rear door window glass

- Rear fixed window glass

- Rear quarter glass

- Rear window defrost grid

- Rear window defrost relay

- Rear window regulator and motor- run and brackets

- Body Control Module (BCM)

- Window control switches

- Windshield glass

The glass, frames and mechanisms include the following:

Edge

- Standard power windows, including one-touch up and one-touch down (LH front window only)

MKX

- Standard power windows, including one-touch up and one-touch down (LH and RH front windows only)

All vehicles

- Liftgate glass which includes the rear window defrost grid and rear wiper arm

- Windshield standard plastic and laminate safety glass

- Windshield glass is bonded to the opening flange with a urethane adhesive

The window control switch:

- is located on each door trim panel.

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

- can manually lower/raise the LH side window (and RH front window on MKX) when the corresponding front window control switch is pressed/pulled and held in the first detent position.

- can automatically lower/raise the driver side window (and right front window on MKX) when the corresponding front window control switch is momentarily pressed/pulled to the second detent position and released.

- has a lock-out feature. When the LH front window lock switch is in the LOCK position, the rear passenger windows only operate from the LH front window control switch.

The accessory delay relay, located in the BCM (Body Control Module), provides voltage for the operation of the power windows and the roof opening panel (if equipped). The accessory delay feature is active when the ignition is in the RUN or the ACC position, or when the ignition is changed from RUN or ACC to the OFF/LOCK position and the LF and RF doors are closed.

Global Open - MKX Only

NOTE: The global open feature may be enabled/disabled by the customer through the message center.

NOTE: If the accessory delay relay is active, the global open feature does not operate.

When a request is received from the Remote Keyless Entry (RKE) transmitter, the BCM (Body Control Module) sends a signal on the global open circuit to both front door window motors (to open the windows) and to the roof opening panel (if equipped; to open the roof opening panel).

Rear Window Defrost

The HVAC module controls the rear window defrost relay (located in the Battery Junction Box (BJB)). The HVAC module activates the rear window defrost relay when the rear window defrost switch (integral to the FCIM (Front Controls Interface Module)) is pressed. If equipped, the rear window defrost can also be activated/deactivated by using a touchscreen interface or voice commands. When the rear window defrost relay is active, the rear window defrost grid is energized.

If equipped, the customer can select different climate control modes/preferences when the vehicle is started using the remote start feature. When the rear defrost is set to AUTO mode, the rear window defrost activates when the outside temperature is less than 0° C (32° F). Once the ignition is cycled to the ON position, the climate control system returns to the previous settings (last ignition ON cycle) and adjustments can be made normally. For additional information on how to set the remote start preferences, refer to the Owner's Literature.
