Understanding the Side Glass Setup on Your Soul
If you have glass damage on the side of your car and are searching for a vent glass replacement, you might run into confusing listings in auto glass catalogs. The third-generation (SK3) vehicle does not have movable or framed mini vent windows inside the door assemblies. Both the front and rear doors use single, full-drop panes of glass without division channels or vertical rubber separator tracks.
What auto glass suppliers and parts databases index as the vent or quarter window is the fixed triangular glass bonded directly into the unibody directly behind the rear passenger door. Because thieves frequently target this smaller pane to gain cabin access, or flying gravel strikes the trailing pillar on the highway, it is the most common side glass requiring total replacement on this model.
Quarter Glass Options, Tints, and Part Identifiers
Unlike earlier models, the fixed rear side glass on this vehicle sits completely flush against the prominent floating-roof design, tucked right up against the distinctive black exterior C-pillar garnish that features the embossed "SOUL" emblem. On the cabin side, the window meets the luggage compartment side trim and the edge of the headliner.
Replacing this window requires matching the correct factory optical tint so the replacement matches your remaining original side windows. Base LX fleet trims generally use clear solar green glass, whereas GT-Line, EX, X-Line, Turbo, and S trims rely on deep privacy glass from the rear doors back. The glass itself remains purely passive: it does not house embedded antenna elements, defroster lines, or perimeter alert sensors.
| Glass Position | NAGS Part Number | Factory Reference | Available Tint Styles |
|---|---|---|---|
| Driver Side (LH) | FQ28181 / FQ28181YP | 87810-K0020 / 87810-K0120 | Solar Green / Factory Dark Privacy |
| Passenger Side (RH) | FQ28182 | 87820-K0020 / 87820-K0120 | Solar Green / Factory Dark Privacy |
Every aftermarket quarter glass I set comes backed by a one-year warranty on the replacement panel itself, coupled with a lifetime guarantee on my installation workmanship so you never have to worry about air drafts or leaks along the unibody seam.
Preventing Wind Whistle Around the C-Pillar
Because the fixed rear quarter glass unit comes pre-encapsulated with its perimeter rubber moulding, achieving an airtight fit against the unibody weld flange is critical. Any gap or irregular contact point behind the plastic C-pillar panel will quickly produce a loud high-speed wind whistle that echoes through the cargo area.
Whenever this glass breaks, tempered shards drop into the rear quarter cavity behind the interior trim panels. I clear out all fragmented glass trapped behind the lower luggage side wall and trunk deck lining so you do not hear annoying internal rattling whenever you accelerate or hit uneven pavement.
