Second Hand Mercedes-Benz A-Class Window Motor

No — the W168 (1997–2004) and W169 (2004–2012) are entirely different generations with different door structures, so their window motors are not interchangeable. Always confirm the exact generation of the donor car matches yours before buying. Quote your registration to the breaker so they can verify the correct fit.

Yes, it matters for the front doors — the 3-door and 5-door variants have different front door dimensions and internals, so the window motors are not the same part. Rear door motors on 5-door cars are specific to the rear doors. Always tell the breaker whether your car is a 3-door or 5-door when asking for a quote.

The W176 ran from 2012 to 2018 and received a facelift in 2015, but whether the window motors changed across that facelift is not something we can confirm with certainty. Name the specific year of both cars when you contact the breaker and ask them to check the part numbers match before purchasing.

Trim level — such as SE, Sport, or AMG Line — does not affect window motor fitment on the A-Class, as the motors are determined by generation, door count, and side (NS or OS) rather than trim. You may find cosmetic differences around the door card or switches between trims, but the motor itself should be the same. Confirm the generation, body style, and side with the breaker to be sure.

Yes, window motors are side-specific — the nearside (NS, passenger/left) and offside (OS, driver/right) motors are not interchangeable. When contacting a breaker, always specify NS or OS clearly alongside your generation and door count so they can supply the correct unit.

No — the W169 (2004–2012) and the W176 (2012–2018) are separate generations with different door and regulator assemblies, so their window motors will not interchange. You need a motor from a W176 donor car, and you should also confirm 3-door or 5-door and NS or OS with the breaker to narrow it down correctly.
