Identifying the Correct Mirror Mount on A34 Windshields
Checking the rearview mirror base is the single step required to determine which replacement glass your car takes. Nissan built the sixth-generation Maxima across two primary glass options: NAGS part FW02389 and NAGS part FW02410. Both options feature the same green tint, integrated blue upper shade band, and approximate dimensions of 1502 mm wide by 1020 mm tall. The difference lies entirely in the mirror mounting bracket bonded directly to the inner surface of the glass.
Base SE trims frequently came equipped with a standard manual day/night flip mirror, which pairs with the standard mount on FW02389. SL trims and SE packages often included an electrochromic auto-dimming rearview mirror with a digital compass display. Some of these heavier, wired auto-dimming units require the alternative bracket configuration found on FW02410. The original factory glass was manufactured by Carlex, typically stamped "NISSAN Carlex" near the bottom edge, corresponding to Nissan dealer numbers 72700-7Y001 or 72700-7Y002.
| Glass Part Number | Rearview Mirror Type | Common Trim Packages |
|---|---|---|
| FW02389 | Standard mechanical flip mirror base | Maxima SE (base interior packages) |
| FW02410 | Alternative bracket for electrochromic compass mirror | Maxima SL and SE with Package |
A-Pillar Mouldings, Roof Seams, and Upper Trim Profiles
The perimeter hardware on this car demands careful handling because the side mouldings do not terminate at the windshield header. Instead, the A-pillar mouldings bridge directly into the longitudinal roof strips running along the roof panel seams. The glass itself uses a dedicated upper reveal moulding—standard aftermarket profile GGG 2389 or WFTF2389—to close the gap against the roof edge.
Because the plastic retaining clips beneath the A-pillar strips become brittle with age, I inspect every roof-to-pillar joint to ensure the side trims seat flush with the new glass. If any moulding fasteners have perished, they must be renewed to stop highway wind noise. Every replacement I complete includes lifetime coverage on my workmanship alongside a one-year warranty on the replacement glass itself. This structural layout stays identical whether your car has the standard steel roof, a traditional sliding sunroof, or the narrow, center-mounted longitudinal Skyview glass panel that runs down the middle of the cabin ceiling.
Managing the Two-Piece Cowl Grille and Cabin Air Intake
At the lower edge of the windshield, the wipers park over a two-piece plastic cowl grille assembly that covers the wiper transmission linkages. Over time, heat exposure deforms this plastic panel, causing the leading rubber lip to curl and lift away from the bottom of the glass. Preserving this seal is critical during a glass swap.
- Cowl warping: A bowed plastic cowl allows high volumes of rainwater to bypass the windshield edge and cascade into the engine bulkhead.
- Cabin water ingress: Directly beneath the passenger-side portion of the cowl sits the fresh-air HVAC intake. If the cowl clips are broken or the panel fails to seat firmly against the new windshield, water will channel straight into the passenger footwell carpet.
- Glass hardware isolation: The glass does not carry embedded heating elements or antenna grids, keeping the bottom edge clean of electrical pigtails and ensuring the focus remains on proper cowl reassembly.
