Identifying Rear Window Features Across Coupe Trims
Pinpointing the exact replacement rear window for your two-door coupe is unusually straightforward because every trim shares an identical rear aperture and glass pattern. Whether your vehicle is a base Pure, a mid-tier Luxe, an early Sport, or the twin-turbo Red Sport 400, Infiniti utilized a single piece of stationary, curved tempered safety glass across the entire production run. You do not have to cross-reference multiple option packages to determine whether you need a different curved pane based on engine size or sport packages.
Every factory piece carries dealer reference number G9700-5CA0A, which crosses over in the aftermarket catalog to NAGS part number FB26569. This means you do not have to look for optional rear wiper holes or external washer nozzles, as none were ever fitted to these coupes. Instead, your inspection comes down to understanding the two critical printed circuits running across the interior surface of the glass:
- Rear Defroster Grid: A continuous horizontal electric heating element bonded onto the inner face of the pane to clear frost and condensation.
- In-Glass Diversity Antenna: Printed conductive lines placed above and alongside the heating grid on the upper glass surface to capture radio signals without an external mast.
- Factory Solar Glaze: Standard light green tint integrated into the glass structure paired with a wide, black ceramic frit perimeter band that protects internal seals from UV rays.
Structural Fit on the CV37 Body
While the front side doors use frameless glass that drops slightly whenever a door handle is pulled, the rear window is solidly mounted directly into the coupe body frame. The top edge bonds beneath the trailing lip of the roof steel, while the side borders follow the steeply raked steel C-pillars down to the trunk deck lid gap. Inside the cabin, the lower portion of the curved glass drops down directly against the rear package tray cover, while the lateral edges sit flush with the interior C-pillar garnish panels and the headliner edge.
Because the angle of the glass drops sharply toward the short rear deck, proper clearance during setting depends on the correct placement of factory-dimension alignment spacers (OEM reference 72714-3NU0A) and the perimeter dam seal (OEM part G2716-89900). These maintain the exact stand-off height required so the glass matches the roof plane without rubbing the painted sheet metal. Whenever I fit this aftermarket glass to your coupe, I back the replacement pane itself with a one-year warranty, alongside lifetime coverage on my workmanship to protect against leaks.
Interior Components Bordering the Rear Glass
The interior architecture around this back glass requires specific attention to the components tucked directly beneath the ceramic frit border:
| Cabin Component | Location Relative to Glass | Function and Details |
|---|---|---|
| Center High-Mount Stop Lamp (CHMSL) | Upper roof header or package shelf border | Third brake light shining directly through the upper non-tinted glass zone |
| Rear Package Tray Cover | Horizontal shelf behind rear seats | Upholstered deck lid panel resting millimeters below the bottom frit edge |
| Interior C-Pillar Garnishes | Left and right interior quarter pillars | Molded pillar trim pieces that frame the inner defroster connector terminals |
Does the Red Sport 400 use a different back glass than the Luxe?
No. Even though the Red Sport 400 features distinct exterior badging, larger exhaust outlets, and extra cooling hardware under the hood, the entire CV37 unibody uses the same glass geometry. A Luxe, Pure, or Red Sport 400 uses the identical glass panel with matching defroster and antenna lines.
Why did my radio reception weaken after applying aftermarket tint?
Because the AM/FM radio antenna is embedded directly onto the inner face of the rear window, using an aftermarket window film containing metallic or carbon-metallic particles can interfere with the radio signals reaching the glass grid. Choosing a non-metallic, ceramic-based tint preserves standard radio reception.
Can broken rear defroster tabs be soldered back onto this glass?
If an electrical tab breaks off the interior defroster grid, soldering directly to the tempered pane risks thermal shock that can shatter the glass instantly. Reattachment requires specialized conductive epoxy rather than standard heat soldering, or a total replacement of the back glass assembly if the printed silver busbar has lifted off the frit.
