Identifying the Correct Liftgate Window on the JX35
Determining the right rear window replacement on this luxury crossover comes down to matching the factory privacy depth and understanding its single-model-year transition into the subsequent QX60 badge. Because this vehicle was produced solely for 2013 on Nissan's L50 platform, its back glass profile is physically identical to the early QX60 liftgates, relying on the structural footprint known under dealer reference 90312-3JA0A. When inspecting the back of your vehicle, you will notice dark privacy glass standard from the factory, which integrates an electrical defroster matrix directly onto the inner surface to melt frost and winter ice.
Unlike some luxury haulers that feature split tailgate glass or multiple glass options based on varying camera or sensor cutouts, the back window on this crossover is a solid, tempered unit. You can verify your setup by checking the wiper pass-through near the lower center edge. The tempered panel requires a precision factory-drilled hole through the lower middle section to seat the rear wiper motor spindle, waterproof rubber isolation grommet, and the articulated wiper arm. If your glass is shattered, you will find this spindle protruding directly from the tailgate structure beneath where the lower edge once rested.
Surrounding Liftgate Hardware and Integrated Components
The back glass does not sit in a vacuum; it is bordered by specific exterior components that distinguish it from the mechanical Nissan Pathfinder sibling. At the top edge, the Center High-Mounted Stop Lamp is integrated straight into the exterior roof spoiler overhang rather than glued against the inner glass face. The glass tucks neatly beneath this upper spoiler lip, flanked on the sides by painted metal pillar frame sections and resting above the wide horizontal chrome liftgate finisher branded with the Infiniti emblem. Around the outer parameter, a dedicated reveal moulding lines the border to transition the glass smoothly into the liftgate cavity.
I handle these replacements entirely through a mobile service that travels directly to your home or workplace across Toronto and the GTA, dealing with the interior panels before setting the new aftermarket pane in place. Accessing the defroster terminals requires careful removal of the three-piece interior tailgate trim, including the upper window header, the side vertical pillar trim mouldings, and the main liftgate hatch panel. The defroster grid uses soldered electrical bus bars positioned along the inner glass edges, which plug directly into the crossover's dedicated wiring harness concealed behind these interior plastic panels.
Ensuring Proper Fit for the Wiper Assembly and Reveal Moulding
Because the original glass is tempered safety glazing, impact fractures reduce the entire rear window into small, granular fragments rather than long laminated cracks. When fitting the replacement back glass, matching the exact hole placement for the wiper spindle is critical to avoid tension against the motor shaft. The wiper motor mounts internally to the inner liftgate sheet metal, and its drive spindle must align perfectly through the replacement glass hole without metal-on-glass contact, relying on a fresh rubber grommet to seal against water ingress into the tailgate interior.
The perimeter reveal seal must sit flush against the tailgate channel so wind noise does not penetrate the quiet cabin typical of the L50 body. While the 2013 badge was quickly retired to make way for the QX60, the rear liftgate geometry remained consistent, meaning the physical curvature, lower chrome finisher overlap, and wiper alignment on the replacement glass must maintain exact factory dimensions to keep the cargo area dry and the rear defroster functioning reliably.
