Distinguishing Sedan Glass from Wagon and Carriage Variants
Checking your vehicle's roofline and body style tells you immediately which rear window replacement you need. Standard four-door sedans take NAGS hardware reference DB10709 or DB11488 (interchangeable with Mopar part 04575915AB or 68026801AA), which features built-in heating elements and an integrated AM/FM radio antenna. If you drive a European Chrysler 300 Touring or a platform-shared Dodge Magnum, your car does not use fixed back glass at all; those wagons rely on a liftgate glass under NAGS DB10712. You must also check whether your sedan has a smooth painted metal roof or an aftermarket padded fabric or simulated vinyl carriage roof, as custom coachbuilt conversions often alter the window opening dimensions compared to the standard factory aperture.
| Body Style / Roof Option | NAGS Reference | Key Glass Features |
|---|---|---|
| Standard 4-Door Sedan | DB10709 / DB11488 | Solar green tint, embedded defroster, integrated AM/FM grid |
| 300 Touring Wagon / Magnum | DB10712 (YPN) | Rear liftgate glass, wiper provision |
Interior Components Surrounding the Rear Window
The sedan's tempered back window relies entirely on in-glass grids for both cabin defogging and radio reception, eliminating the need for an exterior whip antenna. Both circuits terminate at delicate solder tabs along the sides of the glass, concealed behind the interior C-pillar trim panels alongside the radio antenna amplifier module. Whenever I source replacement glass for these cars, I supply aftermarket glass from manufacturers such as XYG, FYG, PGW, or Pilkington that comes with matching grid traces and factory-style electrical connection tabs pre-applied.
Along the bottom edge of the glass, the interior package tray (rear parcel shelf) conceals the lower wiring leads and the third brake light (CHMSL). Unlike many modern vehicles that bond the center high-mount stop lamp directly to the inner surface of the backlite, Chrysler mounted the assembly onto the shelf deck itself, keeping the replacement glass pane completely clear of brackets, camera mounts, or sensor pads.
Addressing Broken Grids and Electrical Tab Detachment
Because the conductive traces for the defroster and antenna are baked onto the inner surface of the tempered glass, they are vulnerable to mechanical damage. Razor blades used during old window tint removal frequently sever the fine copper-ceramic lines, which causes dead spots on the defogger or generates heavy static across AM and FM radio bands. Additionally, the vertical spade terminals located near the C-pillars can snap clean off the glass if snagged during interior detailing.
When sudden glass breakage occurs from road debris or vandalism, the tempered structure breaks into blunt granules that drop past the glass line into the void between the rear seat backrest and the trunk bulkhead. Accessing and clearing this debris requires removing the rear seat cushion and lifting the parcel shelf, which also allows inspection of the lower harness connections before the fresh glass is bedded against the vehicle's rear frame.
