Used Mercedes-Benz Vito Window Winder Motor

No — the W638 (1996–2003) and W639 (2003–2014) are completely different generations with different door structures, so their window winder motors are not interchangeable. Always tell the breaker which generation you have, and confirm against your registration to be certain.

For the front doors, wheelbase makes no difference — those motors are the same across short, long, and extra-long wheelbase variants within the same generation. However, if you need a motor for a sliding rear door, wheelbase can affect the door design on the W639 and W447, so confirm this detail with the breaker before buying.

Ask for the offside (OS) front window winder motor — OS is the driver's side in UK convention. Make sure you also tell the breaker the exact generation (W638, W639, or W447) as the part is door-side specific and will not simply swap between generations.

Trim level does not affect the fitment of a window winder motor on the W639 Vito, as the door frame and mechanism are the same across the range. If a breaker pulls a motor from a different trim, the motor itself will be functionally identical for your door position and wheelbase — just confirm the generation, door side, and door type (front, sliding, or hinged) match yours.

The W639 ran from 2003 to 2014 and received a facelift in 2010; while the core door structure is broadly the same generation, whether the window winder motor interchanges across that 2010 facelift boundary is something you should confirm with the breaker against your exact registration rather than assume.

The W447 (2014 onwards) is a different generation from the W639 (2003–2014) and the two are not compatible for window winder motors, as the door architecture changed between generations. Stick to W447 donor vehicles and give the breaker your registration so they can verify the correct side and door position.
