Second Hand Mercedes-Benz GLB Window Regulator

The GLB (X247) is a single generation launched in 2020, so all UK GLB models sold to date fall within that same generation. There has been a mid-cycle update, but the generation name and platform remain the same throughout. Always confirm the exact year of your donor vehicle with the breaker against your registration to be sure the regulator matches.

The GLB X247 runs as one generation from 2020 onwards, so in principle early and later cars share the same platform. However, mid-cycle revisions can sometimes affect trim-level specifications on components like regulators, so while the generation boundary is not crossed here, you should still confirm compatibility with the breaker using both registrations before buying.

Yes, this is critical — window regulators are side-specific, so a nearside (NS, passenger/left) regulator will not fit the offside (OS, driver/right) door and vice versa. Always tell the breaker exactly which side you need, using NS or OS, to make sure you get the right part.

Trim level does not affect window regulator fitment on the GLB; the door structure and regulator mechanism are the same across SE, AMG Line, and AMG Line Premium variants. You may find minor cosmetic differences in door furniture between trims, but these do not affect whether the regulator itself fits. Just confirm the correct side (NS or OS) and your registration with the breaker.

Yes, because front and rear door regulators are not interchangeable — they are designed for different door sizes and hinge positions. When contacting a breaker, specify whether you need a front or rear regulator, as well as the correct side (NS or OS), to avoid being sent the wrong part.

No — engine and gearbox choice have no bearing on window regulator fitment whatsoever. The parts that matter are the generation (X247), the door position (front or rear), and the side (NS nearside or OS offside), so focus on those details when speaking to a breaker.
