Framed Rear Door Vent Glass on TSX Sedans
The stationary rear door vent glass on this sedan sits directly behind the primary roll-down window, secured within a fully framed door structure rather than being bonded onto an open quarter pillar. Cataloged under NAGS part numbers FV24000 for the passenger side and FV24001 for the driver side, this compact triangular pane is manufactured from green-tinted, solar-absorbing tempered glass that matches the factory heat-rejecting profile of the roll-down side glass. Unlike the cargo-area quarter glass found on the TSX Sport Wagon, the sedan glass operates as a direct component of the rear passenger entrance door. Because it serves solely as an optical and environmental barrier, the pane has no embedded antenna filaments, defroster lines, or perimeter mounting brackets bonded directly to its surface.
Division Bar Mechanics and Surrounding Door Hardware
Holding the pane stationary against the movement of the primary door window is a dedicated vertical metal division bar sash channel. This upright dividing post serves two roles: its forward channel retains the felt run-channel for the descending rear drop glass, while its rearward channel grips the custom-molded rubber quarter channel seal, known under Honda reference 73491-TL0-013 for the left side. Servicing this area requires stripping back the interior rear door panel, releasing the lower inner weatherstrips, and lowering the main window glass off its carrier brackets so the division bar can be unbolted and shifted free from the door frame cavity. When sourcing replacements for shattered factory AGC glass, I source aftermarket units produced by major glassmakers like XYG, PGW, Pilkington, or FYG to match the exact factory glass thickness and solar tint.
Protecting Exterior Sash Trim and Upper Door Mouldings
The perimeter around this triangular vent pane interfaces with rigid upper door frame stampings and sensitive exterior sash trim. Removing the division post and sliding out the molded rubber quarter seal requires deliberate handling of the exterior belt mouldings and lower sash fasteners. These plastic guide clips and black exterior mouldings harden over time and bend out of true if forced, creating wind leaks against the replacement glass edge. The glass itself, designed to align with original factory references like 73405-TL2-A10 on the right side and 73455-TL2-A10 on the left, must seat squarely inside the deep rubber track before the division channel is re-anchored into the bottom of the door shell. Once the metal post is re-bolted to the inner frame and the run channel is reseated, the main window regulator can cycle without binding against the vent glass frame.
