Break-Ins and the Rear Door Stationary Window
Most Passport owners contact me regarding this small side glass after a smash-and-grab incident. Because the cargo hold behind the rear seats sits right in view, thieves frequently punch out the rear passenger door vent glass hoping to reach in, pop the door locks, or drop the rear bench without setting off impact sensors. It leaves a mess of pebbled tempered safety glass tucked deep inside the framed door shell.
Every trim in the lineup—from the entry Sport and volume EX-L up to the Touring, Elite, and rugged TrailSport—uses the exact same dark privacy tint on this rear door vent glass. Unlike the acoustic laminate glass used on the front doors of higher trims to block highway buffeting, this rear quarter piece is single-pane tempered solar-absorbing glass. It carries no defroster grids, embedded antennas, or wiring harnesses, but replacing it requires disassembling the door cavity to address the hardware holding it in place.
Shared Door Architecture with the Third-Gen Pilot
While this vehicle features a truncated rear overhang and custom body glass behind the C-pillar compared to the three-row Honda Pilot (2016–2022), both vehicles share identical rear passenger side doors. The framed door structure, run channels, and glass dimensions are completely cross-compatible between both models.
| Component Description | Left Side (Driver) | Right Side (Passenger) |
|---|---|---|
| Rear Door Vent Glass (Dealer Ref) | 73455-TG7-A20 | 73405-TG7-A20 |
| Vertical Division Sash Bar | 72771-TG7-A11 | 72731-TG7-A11 |
| Encapsulating Rubber Run Channel | 73491-TG7-A12 | 73441-TG7-A12 |
The glass sits directly adjacent to the main roll-down door window, isolated by an upright vertical division bar. When I replace this glass for clients at their home driveway or workplace parking space across Toronto and the GTA, I dismantle the inner door card and lower mounting points so the replacement glass seats true into the rubber channel without pinching.
The Vertical Division Bar and Wind Noise Complaints
On community forums, drivers occasionally track down an annoying cabin flutter or buzz to the rear door pillar. The root cause is almost always mechanical play along the division sash. The vertical divider is held at the bottom frame by an M6 bolt and collar assembly, while the top uses countersunk flat screws (part 93600-04008-0A).
- Hardware alignment: If that lower M6 anchor or the top retaining screw shifts out of alignment, the division bar twists slightly, breaking the seal against the drop-down window.
- Channel distortion: The molded rubber weatherstrip must seat evenly into the metal sash. If forced or twisted during a hurried replacement, air slips past the division edge at highway speeds.
- Hidden debris: When the original tempered glass shatters, shards fall directly down into the sash base and bottom door cavity. Clearing this debris entirely is essential so the window regulator tracks cleanly and the new vent glass settles firmly against the lower stop.
