Glass, Frames and Mechanisms

The glass, frames and mechanisms consist of the:

• front door window glass.
• front door window motor.
• front door window regulator.
• rear quarter window glass.
• rear quarter window glass frame.
• rear quarter motor and window regulator.
• rear door window glass.
• rear door window motor.
• rear door window regulator.
• liftgate glass.
• windshield glass.

The glass, frames and mechanisms include:

• standard plastic and laminate safety glass.
• liftgate glass.
• windshield glass which is bonded to the opening flange with a urethane sealant.
• on Expedition, standard power windows which include one-touch up/down (LF only) and lock out feature.
• on Navigator, standard power windows which include one-touch up/down (LF and RF only) and lock out feature.
• power vented rear quarter windows or fixed rear quarter windows.
• RH quarter window glass antenna.

The window regulator control switch:

• is located on each door trim panel.
• may be used to raise or lower all windows from the master control on the driver side, or the individual side window from the individual door switch.
• on Expedition, includes a one-touch up and one-touch down double detent feature (LF only).
• on Navigator, includes a one-touch up and one-touch down double detent feature (LF and RF).
• can lower the driver side window when the master control is depressed halfway (first detent).
• completely lowers the driver side window when the master control is fully depressed and then released (second detent).
• completely raises the driver side window when the master control is pulled up and then released (second detent).
• on Navigator, will completely lower the passenger front window when the RF control switch is fully depressed and then released (second detent).
• on Navigator, will completely raise the passenger front window when the RF control switch is pulled up and then released (second detent).
• has a lock-out feature. On Expedition, when the LF window lock-out switch is in the LOCK position, the front passenger and rear passenger windows only operate from the LF window control switch. On Navigator, when the LF window lock-out switch is in the LOCK position, the rear passenger windows only operate from the LF window control switch.

The rear quarter glass regulator control switch:

• is located in the overhead console.
• may be used to open and close the RH or LH rear quarter windows.
• stop the rear quarter glass in any position when released.

The power window system will operate if the ignition is in the RUN or ACC mode, or the delayed accessory feature is active.

Passenger windows may be raised or lowered using the LF master control switches or the appropriate passenger window switch. Passenger window switches receive power when the delayed accessory relay is active and the LF remote lock-out switch is in the UNLOCK position. When in the LOCK-OUT position, all passenger window control switches are deactivated (Expedition only). When in the LOCK-OUT position, the rear window control switches are deactivated (Navigator only).

The accessory delay relay, located in the BCM, provides power for the operation of the power windows and the roof opening panel (if equipped). For Expedition (LF window only) and Navigator (LF and RF windows), the accessory delay relay provides a low current signal to allow window movement. The accessory delay relay is active when the ignition is in the RUN or the ACC mode, or when the ignition is changed from RUN or ACC mode to the OFF mode and the LF and RF doors are closed.

The accessory delay relay deactivates when:

• the LF or RF door is ajar and the ignition is in the OFF mode.
• 10 minutes have elapsed since the ignition was changed from ACC or RUN mode to the OFF mode.

The HVAC module controls the state of the rear window defrost relay. When the rear window defrost switch (integral to the FCIM module) is pressed, the FCIM sends a message to the HVAC module to activate the rear window defrost relay. When the rear window defrost relay is active, both the rear window defrost grid and heated mirror elements will be energized.

The HVAC module will deactivate the rear window defrost relay when one of the following conditions is met:

• The rear window defrost switch is pressed when the feature is active
• Ignition state is changed from RUN to OFF mode
• The 10 minute timing function is completed
