Electric Power Window Master Switch for Mercedes-Benz Viano Vito W639

Restore precise control over every cabin window with this replacement Electric Power Window Master Switch, engineered exclusively for the Mercedes-Benz Viano and Vito W639 platform. As a direct substitute for OEM part number A6395451013, this front-left door module resolves frequent operational failures such as unresponsive window lifts, cracked switch contacts, or malfunctioning lifters that disrupt daily driving and maintenance routines.
