Fixed Quarter Glass Placement in the Jaguar D-Pillar Body Aperture
Replacing the rear vent window on this compact crossover involves working directly against the steel body frame rather than inside a door shell. Jaguar built the E-Pace on the X540 platform with conventional framed rear passenger doors, which leaves this smaller triangular side glass permanently bonded into the rear quarter pillar adjacent to the loadspace. Because the glass is set into the body stamping right where the roofline drops down toward the tailgate, precision around the surrounding panels is critical.
The interior edge of the aperture is enclosed by the cargo area side trim, luggage compartment upper panels, and the lower D-pillar lining. Replacing this unit means accessing and unseating the internal cabin fasteners around the parcel shelf guides without warping the plastics. Many drivers mistake a buzzing noise in the rear cabin for loose window glass, but on this model, that sound is frequently an unclipped interior trim section or a misaligned parcel shelf runner right beside the glass recess.
Factory Glass Variants, Tint Densities, and Part Numbers
Jaguar equipped this vehicle with two primary glass appearances depending on the exterior trim level and options. Base configurations generally feature clear or green-tinted solar glass, whereas higher models like the R-Dynamic SE or HSE come standard with deep factory privacy tint. There are no defroster lines, camera mounts, or wash-wipe assemblies attached to this window, making accurate glass identification strictly about body side, tint level, and supersede references.
| Glass Identification Component | Specification & Factory Detail |
|---|---|
| Direct Part Number (Driver Side / Left) | J9C41264 |
| Superseded Part Number Reference | J9C4776 |
| Material Composition | Tempered safety glass with baked ceramic frit band |
| Available Glass Tints | Light solar green (base) / Dark privacy tint (R-Dynamic/packs) |
Every replacement window I supply is protected against manufacturing flaws for one year, while my labor and structural seal against water intrusion are backed for the entire lifetime of the vehicle. When matching an aftermarket replacement to an original factory unit, I check the ceramic frit border width carefully to guarantee complete visual coverage of the interior pinchweld lip.
Belt Mouldings, Black Pack Finishes, and Surrounding Weatherstrips
The lower edge of the quarter vent rests directly above the vehicle waistline trim. On an E-Pace fitted with the standard bright exterior package, this is a polished satin chrome moulding; models specified with the factory Black Pack feature a high-gloss Narvik Black moulding instead. Both versions sit unusually tight against the bottom perimeter of the glass.
The exterior rubber surround encapsulating the glass edge is exceptionally soft. A common issue during salvage or botched glass removals is scarring this exterior perimeter rubber or scratching the gloss waist finisher. Preserving these adjacent exterior seals demands that the painted quarter panel and waistline tracks remain undisturbed so the new glass sits flush with the rear door glass plane and eliminates exterior wind turbulence along the rear pillars.
