Identifying the Correct Door Glass for Your Altima
To determine exactly which replacement glass panel belongs on your car, you only need to identify which side and row suffered the break, because Nissan standardized the solar-tinted glass across every standard L33 trim level, including the 2.5, 2.5 S, 2.5 SV, 2.5 SL, and the 3.5-liter V6 variants. Unlike the front windshield which houses specialized brackets, none of the roll-down door windows carry integrated rain sensors, camera cutouts, or embedded defroster lines. Every factory unit relies on a uniform green solar-control tempered pane mounted inside a fully framed stamped-steel window frame.
The only critical distinction lies between positions: the front driver and passenger doors feature larger drop glass that glides down directly against the inner waist weatherstrip, while the rear doors utilize a distinct two-piece setup. On the rear doors, the movable window pane sits alongside a stationary vertical division bar that partitions the roll-down glass from the fixed triangle vent window near the C-pillar.
| Door Position | Original Nissan Part | Superseded Factory Number |
|---|---|---|
| Front Left (Driver) | 80301-3TA0A | 80301-9HT0A |
| Front Right (Passenger) | 80300-3TA0A | 80300-9HT0A |
| Rear Left (Driver Side) | 82301-3TA0A | 82301-9HT0A |
| Rear Right (Passenger Side) | 82300-3TA0A | 82300-9HT0A |
Mechanical Hardware and Common Door Cavity Issues
Once inside the door cavity, the bottom edge of the glass features bonded mounting brackets secured directly to a cable-and-drum electric window regulator carriage using hex fasteners. When an Altima window drops into the door or rolls up crookedly, the culprit is often a cracked plastic regulator guide clip rather than damaged glass itself. When replacing broken glass panels on these cars, I supply aftermarket glass sourced from reliable manufacturers such as Pilkington, PGW, FYG, or XYG, ensuring the tempered pane fits properly into the existing run channels.
A critical detail specific to 2015 to 2017 Altima sedans involves Nissan recall PC675. In these model years, factory rear door vapor barrier sealing screens were routed in a way that could catch on the inner door latch release cable when the rear glass descended to its lowest position. If that plastic vapor barrier contacts the cable while the window operates, it can inadvertently pop the rear passenger door open. Whenever the door trim panel, inner weatherstripping, and vapor barrier are detached to clear out tempered glass fragments, checking this clearance avoids an unexpected latch malfunction.
Run Channel Resistance on Framed L33 Doors
Because the L33 doors use deep rubber run channels embedded inside rigid steel door sashes, road grime and shattered glass bits frequently lodge in the upper corners. If these rubber guide paths become deformed or pinched, the increased drag creates excessive friction against the rising glass edge. When that occurs, the power window motor senses resistance and triggers the factory anti-pinch auto-reverse function, forcing the window back down before it seats into the top frame.
