Identifying the Front Door Vent Glass on Your Crosstrek
When you look at the small triangular window ahead of your front roll-down window, you might wonder whether your specific trim level—whether it is a Base, Premium, Sport, Limited, or Hybrid—requires a specialized piece of glass. Fortunately, Subaru kept this design uniform across the entire 2018–2023 production cycle. You do not have to check for built-in antenna wires, defroster lines, or driver-assist sensors, as none of those electronics pass through this piece. Every factory variant uses green solar-tinted tempered glass designed to match the adjacent drop-down door windows.
You can identify the exact replacement part through industry-standard numbering systems stamped on aftermarket inventory:
- Driver Side (Front Left): NAGS part number FV27691GT (or FV27691), corresponding to Subaru dealer reference 61012FL110.
- Passenger Side (Front Right): NAGS part number FV27690GT (or FV27690), corresponding to Subaru dealer reference 61012FL100.
Because the body structure of this crossover shares its front door architecture with the fifth-generation Impreza and the VB WRX, the glass dimensions and hardware mounting points are identical among those vehicles.
Framed Channel Architecture and Surrounding Hardware
Unlike the glued-in quarter windows at the rear of the cabin, this front partition pane relies entirely on a mechanical dry fit. The glass sits inside the full upper window frame of the door shell rather than adhering directly to bare metal with urethane. It slots into a molded rubber channel—the 61284FL weatherstrip series—and is secured at the back edge by a vertical division bar sash that separates the stationary triangle from the moving front window.
I operate entirely as a mobile service across Toronto and the GTA, replacing this partition glass right in your driveway or workplace parking spot without requiring a shop visit. Servicing the glass means taking off the interior door trim panel to loosen the lower mounts of that internal division bar, which allows the rubber channel to release the damaged glass without stressing the surrounding door frame. The side mirror assembly is bolted straight through the outer door sheet metal nearby, so it stays untouched on the exterior during the work.
Common Owner Questions
Does the eyesight camera system require attention when this window breaks?
No. The front door vent window has no connection to the EyeSight safety cameras mounted at the top of the windshield. It contains no electronic sensors, rain monitors, or heating elements, meaning the mechanical replacement of this pane involves no software or electronic adjustments whatsoever.
Why is there wind whistling near the mirror after a partition glass issue?
The glass must seat fully inside the deep groove of the division bar sash and the outer perimeter weatherstrip run. If the partition sash was knocked slightly out of alignment when the glass broke, or if the rubber run seated unevenly during reassembly, highway speeds will push high-pressure air through the microscopic gaps around the seal.
Is this front vent window made of laminated or tempered glass?
The front partition glass on this vehicle is tempered glass featuring a solar-green tint. When broken, it fractures into small, blunt granules rather than cracking into large shards like a laminated windshield.
