Mercedes Benz Window Regulator A6397200446S 6397200446

The TinzerMotor A6397200446S Power Window Regulator with Motor Assembly is a premium, heavy-duty replacement system engineered for commercial vans, fleet transporters, and heavy-use professional vehicles. Manufactured by Wenzhou Ruishuo Auto Parts (Tinzer), this complete assembly combines a high-torque electric motor and a structurally reinforced regulator panel into a pre-assembled, drop-in kit for rapid fleet maintenance.

• Engineered Drive Synergies: The heavy-duty 12V motor is precision-calibrated directly to the Bowden cable drum at the factory, eliminating the gear-slippage and cable-binding problems often caused by mixing separate aftermarket components.

• Endurance Cycling Profiles: Complete assemblies are tested through thousands of uninterrupted up-and-down structural lifecycles inside localized test doors under continuous artificial weight loads to prevent premature fatigue.

• Harsh Environment Validation: Units endure rigorous thermal shock testing (operating flawlessly from -40°C up to +80°C) alongside moisture-seal verification to withstand industrial power-washing, road salts, and unpredictable weather.

• 100% Final Inspection: Prior to final crating, every pre-assembled kit goes through automated current-draw and tracking alignment tests to deliver zero-defect, plug-and-play installation right out of the box.
