- Front door window regulator and motor

- HVAC module

- Rear door fixed glass and top run

- Rear door glass run retainer

- SJB (Smart Junction Box)

- Windshield glass

The glass, frames and mechanisms include the following:

- Standard plastic and laminate windshield glass

- Rear window glass, which houses the rear defrost grid and rear wiper

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

- Standard power windows, which include one-touch up, one-touch down and lock-out feature (left front only)

The window regulator control switch:

- is located on each door trim panel.

- may be used to 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 passenger front and rear window control switches when the lock-out switch on the left front window control switch is turned on.

- can automatically lower the driver door window when the window control switch is momentarily pressed into the second detent position and released.

- can automatically raise the driver door window when the window control switch is momentarily pulled to the second detent position and released.

Delayed accessory feature

The accessory delay relay, located in the SJB (Smart Junction Box), provides power for the operation of the power windows, radio and the power moon roof (if equipped). 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.

Rear window defrost

The HVAC module controls the state of the rear window defrost relay. When the engine is running and the rear window defrost switch (integral to the Front Controls Interface Module (FCIM)) is pressed, the HVAC module will 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.
