Identifying Your Roof Glass Setup and Factory Options
Pinpointing the correct replacement panel for this roof comes down to checking whether your vehicle was built with a factory-installed power sliding unit or left the line with a solid steel roof. On Limited and Overland packages, the single-pane electric tilt-and-slide glass assembly was fitted standard at the factory, whereas on the Laredo and high-output SRT8 editions, it had to be checked off as an optional add-on. If your vehicle has the overhead switch pack operating the glass, the assembly uses an integrated factory solar privacy tint designed to cut cabin heat, paired with a vulcanized rubber perimeter encapsulation seal permanently molded around the edge of the glass itself.
Mopar cataloged this exact moveable glass under part numbers 05139931AA and the revised 05139931AB, which cross-references in the auto glass system under NAGS part number SR10955. Because it is a modular, single-pane pane that tilts up and slides internally between the outer sheet metal and the headliner, there are no wire harnesses, embedded aerial antennas, defroster grids, or forward-facing rain sensors attached to the glass panel. When I source replacements for this model, I rely strictly on top aftermarket options manufactured by Pilkington, FYG, PGW, or XYG rather than paying dealer markups for factory boxed crates.
Hardware Details and Structural Cassette Components
Unlike fixed quarter glass or bonded rear glass, this panel mounts directly to the mechanical guide tracks inside the roof cassette. Accessing the mounting points involves unclipping the flexible accordion-style side trim valances inside the cabin to expose four Torx-head screws—two positioned on the driver side bracket and two on the passenger side. These fasteners allow the glass to be mechanically aligned to the roof aperture before locking it down, preventing road wind buffeting over the leading edge.
Directly beneath the glass pane, a manually sliding sunshade with molded ventilation louvers runs along the lower guide rails, upholstered to match the interior headliner fabric. At the front opening edge of the cassette frame, a spring-loaded mesh wind deflector automatically flips upward when the glass retracts into the roof pocket, preventing buffeting sounds at highway speeds. A dedicated drive motor with built-in pinch-protection logic controls the movement; if the battery has been disconnected during cabin repairs, the motor occasionally loses its home position and requires a straightforward button-hold reset sequence to re-engage auto-close operation.
Preventing Water Intrusion Around the Glass Encapsulation
Severe cabin leaks on this platform are almost universally tied to the relationship between the perimeter edge seal and the internal drainage plumbing. The molded rubber weatherstrip bonded to the glass panel is not designed to be completely watertight; it acts as a primary barrier to deflect the bulk of rainwater, relying on an internal collection tray underneath to catch whatever slips past. From that plastic tray, four corner spouts direct water through flexible hoses running down the front A-pillars and the rear pillar cavities, exiting behind the front fender liners and lower kick panels.
When the vulcanized seal around an old panel begins to shrink, warp, or crack from prolonged sun exposure, the volume of water entering the track cassette easily exceeds what the gravity-fed lines can displace. Compounding this, the factory drain fittings have a history of backing up from debris or sliding completely off the drip tray barbs if someone attempts to clear them with high-pressure air or stiff wire rods. When that happens, runoff bypassed by the compromised glass edge leaks straight through the overhead dome lights, soaks into the front grab handles, and saturates the passenger footwell carpet.
