Mercedes-Benz GLB Window Switch Replacement Parts

The GLB is a 5-door SUV throughout its range, so door count isn't a variable here, but you do need to specify which door the switch is for — NS (nearside, passenger side) or OS (offside, driver side) — plus whether you need a master switch for the driver's door or a single-window switch for a rear door. The GLB (X247) launched in 2019 and received a facelift in 2023, so you should also confirm which version you have, ideally by providing your registration to the breaker so they can match the exact part.

This is an important question because the GLB X247 was facelifted in 2023, and interior trim and switch designs can change at that point — a pre-facelift switch from 2019–2022 may look or function differently to a post-facelift unit from 2023 onwards. Crossing that facelift boundary is something you should confirm directly with the breaker, giving them your registration number so they can verify compatibility against the exact part number.

Trim level — whether Sport, AMG Line, or AMG Line Premium — does not typically affect the fitment of a window switch, as the switch mechanism relates to the door and window hardware rather than the specification package. You may find minor cosmetic differences such as switch surround finish or illumination style between trim levels, but these are aesthetic rather than functional fitment concerns; confirm with the breaker if a specific appearance is important to you.

No — the driver's (OS, offside) door typically houses a master switch panel controlling all windows, whereas the front passenger (NS, nearside) and rear doors each have a single-window switch, so these are different parts and are not interchangeable. Always tell the breaker which specific door position you need, as supplying the wrong side will mean the part won't fit or won't function correctly.

Engine choice — whether diesel or petrol, and whether the car is 4MATIC or front-wheel drive — does not affect window switch fitment, as these switches are door-mounted components unrelated to the drivetrain. What matters is the generation (pre- or post-2023 facelift) and the door position (OS/NS, front or rear), so focus on those details when speaking to a breaker.

Within the pre-facelift X247 generation (2019 to 2022), window switches for the same door position are generally likely to be compatible, but minor running changes during a production run can occasionally affect connectors or switch layouts. It's always worth confirming with the breaker using your registration number to ensure the part number aligns, rather than assuming all pre-facelift years are identical.
