Side Window Construction on the GP and GJ Impreza
When a side window breaks on this car, the clean-up reveals a distinct setup compared to older Subarus. Unlike the classic frameless doors found on earlier models, these cars use fully framed window channels. Up front, the glass is split: a small, fixed triangular vent glass (dealer reference 61012FJ200 for the right or 61012FJ210 for the left) sits forward of a vertical division bar, while the primary roll-down window slides behind it.
Every movable door pane is single-layer tempered safety glass finished with a light green solar tint. The front passenger drop glass corresponds to NAGS number FD25463 (Subaru OEM 61011FJ000 or 61011FJ001), while the front driver side is FD25464 (OEM 61011FJ010 or 61011FJ011). In the rear, the driver side door takes FD25471 (OEM 62011FJ010/011) and the passenger side uses FD25470 (OEM 62011FJ000/001). Because these panes carry no defrost grids, integrated antennas, or embedded sensors, the glass itself relies entirely on accurate edge geometry to seat into the run channels.
For every replacement job on these doors, I source high-grade aftermarket glass manufactured by trusted suppliers like Pilkington, FYG, PGW, or XYG to ensure it matches the original green solar tint and factory thickness. These exact front and rear movable panes also share direct interchangeability with the 2013–2017 Subaru XV Crosstrek, which shares the identical door shell stamping.
Regulators, Mounting Brackets, and Window Travel Issues
The door glass mounts directly to the cable-operated window regulator using integrated bottom sash brackets secured with 10mm bolts. If your window suddenly fell inside the door prior to shattering, the cause was almost certainly a failure of the regulator's plastic carrier sliders or a snapped cable rather than an issue with the glass track itself.
The tight tolerances inside the rubber door run channels frequently cause slow operation or binding. Road dust and dried silicone build up along the vertical division channel and outer belt moulding, creating friction that triggers the motor's safety stop. When a new pane is bolted in, the power window motor often needs an auto-reverse reset sequence at the driver switch, or the glass will hit the upper frame and automatically roll itself halfway back down.
| Glass Position | NAGS Number | OEM Reference |
|---|---|---|
| Front Driver (LH) | FD25464 GTN | 61011FJ010 / 61011FJ011 |
| Front Passenger (RH) | FD25463 GTN | 61011FJ000 / 61011FJ001 |
| Rear Driver (LH) | FD25471 GTN | 62011FJ010 / 62011FJ011 |
| Rear Passenger (RH) | FD25470 GTN | 62011FJ000 / 62011FJ001 |
Why does the window roll back down after reaching the top?
The pinch-protection system relies on motor resistance monitoring. If the battery was disconnected or the glass was moved while unbolted, the master control module loses its baseline stroke position. It mistakes the resistance of seating into the upper rubber weatherstrip for an obstruction and reverses travel. Holding the switch up until the glass closes, then continuing to hold it for an additional two to three seconds, resets the limit memory.
Can I swap glass between a 5-door hatchback and a 4-door sedan?
Yes. The front and rear side door drop glass panes are identical across the 2012–2016 GJ sedan and GP hatchback variants. Both body styles share the same door frames, division bars, sash attachments, and regulator bolt spreads.
