Matching the Correct Back Glass on the Maxima
Identifying the rear glass for this sedan is remarkably straightforward compared to most modern sedans, because Nissan utilized a single standardized rear window layout across the entire production run. Whether you drive an entry-level S, an SV, SL, the sporty SR, or the fully optioned Platinum, the physical opening and glass parameters remain identical. In the aftermarket automotive glass catalog, this part is cataloged under the National Auto Glass Specifications standard as NAGS number FB26476 (frequently labeled FB26476GT), which mirrors the physical fit of factory dealer part 79700-4RA1A.
While the exterior dimensions never fluctuated between model years, verifying your glass setup requires checking what is embedded directly into the pane:
- Integrated Heating Lines: A horizontal electrical defroster grid is baked into the tempered safety glass to clear frost and condensation.
- Internal Radio Antenna: Rather than using a secondary mast on the quarter panel, the AM/FM radio receiver is printed directly into the upper bands of the glass grid, powered by dedicated solder terminals along the interior borders.
- Factory Tint Hue: The pane comes standard with an embedded solar green / dark tint profile, eliminating the need to match clear vs. tinted variants.
- Absence of Add-ons: You will not find camera cutouts, wiper grommets, or encapsulated exterior rubber moldings on this rear window, as the perimeter sits completely flush against the steel frame.
The Floating Roof Design and C-Pillar Appliqués
Nissan's signature styling feature on this body style is the "floating roof" aesthetic, which directly affects how the back glass aligns with the exterior sheet metal. The edges of the back window sit recessed directly against the gloss-black plastic appliqué panels fixed to the C-pillars. These panels create a continuous visual strip of dark glass and trim connecting the side profile to the rear window. Whenever I replace this stationary rear panel, I protect your investment with a one-year warranty on the replacement glass itself alongside a lifetime guarantee covering my workmanship against water intrusion or air leaks.
Because the rear glass is bonded directly within this recessed channel, clearing out shattered tempered glass from a broken window requires thorough attention around the parcel shelf. On Platinum trims equipped with the power rear sunshade, the shade runs along tracks inches from the inside glass surface, making it essential that the shelf area remains completely clear of loose debris before the new window is dropped into place.
Addressing Factory Adhesion Recalls and Grid Failures
Physical breakage from road debris or vandalism is not the only reason this rear window gets replaced. Nissan issued a widespread safety recall (campaign reference PC752) specifically targeting select 2020 production models—including the Maxima, Altima, and Leaf—due to rear window glass that lacked adequate urethane adhesion from the factory, which could cause the window to loosen or detach over time.
Another frequent issue involves the conductive electrical solder tabs that supply current to the defroster and antenna lines. Over years of thermal cycling, these soldered terminals can break away entirely from the inner face of the window. While small breaks in a single heating line can sometimes be bridged with conductive paint, a sheared-off terminal tab on the glass substrate often makes a full back glass replacement the only reliable way to restore both rear defogging and radio reception.
Does my trim package change the back glass part number?
No. From the base S trim up through the SV, SL, SR, and Platinum, every model uses the exact same NAGS FB26476 back glass. Interior options like the motorized rear sunshade on Platinum models reside on the rear deck rather than attaching to the glass itself.
Can broken defroster tabs on the back window be reattached without replacement?
If a defroster or antenna solder tab snaps off the surface of the glass, conductive epoxy kits rarely hold up under the electrical load required to heat the pane. In most cases where the copper pad has torn away from the glass, installing a new back window is necessary to regain a functioning defroster and antenna.
