Identifying the Correct Liftgate Glass for Your Compass
Determining which rear window belongs on your Jeep Compass comes down to evaluating the factory tint level on the liftgate. While every rear window for this vehicle shares the exact same exterior perimeter and single-piece tempered design, Mopar cataloged distinct glass panels depending on the vehicle trim. Base Sport models and fleet builds typically left the assembly line with light solar green glass under part numbers like 55112803AA and 55112803AB. In contrast, higher packages like the Latitude, Limited, and Trailhawk feature deep factory privacy glass, tied to part numbers such as 55112797AA, 55112797AB, and 5074912AI. You can quickly verify yours by looking through the rear quarter glass next to the cargo area; if your cargo side windows are dark enough that you cannot see clearly into the trunk from outside, your rear liftgate requires the matching privacy-tinted replacement rather than the clear solar variant.
You do not need to worry about structural glass changes if your vehicle has the dual-pane panoramic sunroof option or the standard steel roof, because the rear hatch aperture remains identical across all roof builds. Similarly, while forward-facing ADAS cameras and rain sensors affect the front windshield, the liftgate window functions independently of those active safety systems. All back glass panels for this build feature an integrated heating grid with printed horizontal lines across the inner surface, along with a precut hole centered near the bottom edge designed to house the rear wiper motor spindle and its protective rubber grommet. On many factory panels, you might also spot the subtle Loch Ness Monster graphic stamped into the lower black ceramic frit band.
Hardware Details and Structural Liftgate Components
The back glass on this liftgate sits inside a recessed steel frame flanked by specific exterior trim components. Framing the top and sides of the glass are aerodynamic side applique moldings and an upper liftgate spoiler that incorporates the center high-mount stop lamp. Because the third brake light sits entirely within the plastic roof spoiler overhang, it never adheres to the glass surface itself. Beneath the glass, the wiper arm attaches directly through the pre-drilled glass opening, secured against an exterior rubber weather seal that isolates the wiper motor shaft from the cabin interior.

Addressing a broken rear window on this hatch requires carefully unsnapping the interior liftgate trim panels to reach the electrical spade terminals that power the defroster elements. These plastic inner covers conceal the wiring harness routed along the inner hatch pillars, ensuring the ground and 12-volt power connections hook securely into the heating grid once the new aftermarket panel is positioned into the liftgate frame.
Defroster Grid Connections and Irreparable Tab Failures
A frequent reason drivers seek a new rear window on this vehicle involves electrical failure at the defroster solder points rather than impact damage. The electrical power leads snap onto small metal bus bar tabs mounted directly against the inner face of the glass. Over time, physical stress from shifting cargo or thermal shock can cause these metal tabs to tear loose from the panel. If the tab simply detaches from the electrical contact point, it is sometimes salvageable using a specialized silver-bearing conductive epoxy alongside replacement terminal tab 68428688AA.
However, total glass replacement becomes unavoidable when the failure pulls the underlying conductive ceramic material off the glass substrate. When the brown or silver bus bar trace printed along the perimeter frit tears completely off the glass core, electrical continuity is permanently severed. Solder and conductive adhesives cannot bond directly to bare glass, rendering the rear defogger completely inoperative across the entire hatch. In those situations, installing a fresh rear window is the only method to restore winter defrosting performance across the liftgate.
