Windows and Glass: Description and Operation

Glass, Frames and Mechanisms

NOTE: The Smart Junction Box (SJB) may also be identified as the Generic Electronic Module (GEM).

The glass, frames and mechanisms consist of:

- accessory delay relay.
- door window regulator motors.
- Front Controls Interface Module (FCIM).
- front door glass top run.
- front door window glass.
- HVAC module.
- rear door window glass.
- rear window defrost grid.
- rear window defrost relay.
- rear window glass.
- rear fixed window glass.
- rear window regulator and motor - run and brackets.
- SJB.
- window control switches.
- window regulators.
- windshield glass.

The glass, frames and mechanisms include:

- standard plastic and laminate safety glass.
- windshield glass which is bonded to the opening flange with a urethane adhesive.
- for MKZ, standard power windows which include one-touch up and one-touch down features (left front and right front only).
- for Fusion and Milan, standard power windows which include one-touch up and one-touch down features (left front only).

The window regulator 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 lock out rear window control switches when the lock-out switch on the left front window control switch is turned on.

The accessory delay relay, located in the SJB, provides power for the operation of the power windows. The accessory delay feature is active when the ignition switch is in the RUN or the ACC position, or when the ignition switch is changed from RUN or ACC to the OFF/LOCK position and the LF and RF doors are closed.


Global Open - MKZ Only

NOTE: The global open feature may be enabled/disabled via scan tool or in some cases modified by the customer following a procedure listed in the vehicle Owner's Literature. For a complete list of available programmable parameters, refer to the Module Configuration and Parameter Chart in Information Bus. Principles of Operation

The SJB sends a signal on the global open circuit, to both front door window motors and the roof opening panel motor, to open or close the windows based on a signal received from the Remote Keyless Entry (RKE) transmitter. If the accessory delay relay is active, the global open feature will not operate.


Rear Window Defrost

For MKZ, the rear window defrost switch is integral to the FCIM. For Fusion and Milan, the rear window defrost switch is integral to the HVAC module or FCIM if equipped with navigation system. When the rear window defrost switch is pressed, the HVAC module will activate the rear window defrost relay. When the rear window defrost relay is activated, the rear window defrost grid will be energized.
