Interchange Fitment FAQs
A: All Window Regulator, Rear options shown on this page are matched to your selected configuration:
2021 Mercedes A-CLASS.
Used OEM parts are dismantled from donor vehicles as complete assemblies, and a specific interchange fitment is assigned during this process.
Every detail shown in the fitment notes must match your vehicle exactly.
A: An interchange fitment option defines the exact donor vehicle configuration your part came from. For 2021 Mercedes A-CLASS, this may include engine size, VIN code,
transmission model, drivetrain, axle ratio, and other critical identifiers. This data comes from VIN decoding, OEM information, and
physical inspection of the donor vehicle.
A: Used OEM parts are not universal. If any fitment detail for your 2021 Mercedes A-CLASS differs from what is shown in the fitment notes,
the Window Regulator, Rear may not install, communicate with your vehicle, or function correctly. Always verify all fitment details before ordering.
A: Fitment information is captured when the donor vehicle is dismantled.
The yard decodes the VIN for 2021 Mercedes A-CLASS, checks OEM data and interchange databases,
and verifies details during physical inspection. The resulting fitment is then assigned to the Window Regulator, Rear assembly.
A: Many 2021 Mercedes A-CLASS vehicles were built with multiple configurations in the same year and trim. Trim name alone (XLT, Limited, Sport, etc.) is not enough.
You must match the exact configuration shown in the fitment notes—such as engine size, transmission type, drivetrain, and axle ratio—before selecting a Window Regulator, Rear.
A: You can find the VIN for your 2021 Mercedes A-CLASS on
the driver-side dashboard (visible through the windshield), inside the driver-side door jamb, and on your registration or insurance documents.
The VIN helps confirm the correct configuration and fitment.
A: Yes. Trim levels on your 2021 Mercedes A-CLASS can affect electronics, sensors, body parts, and interior components. Always match the detailed fitment notes for your configuration,
not just the trim name, before selecting a Window Regulator, Rear.
