Mercedes-Benz W176 (2014-2018) Rear Window Regulator & Motor | Genuine Replacement

Description

If your rear window is stuck, making a grinding noise, or moving slowly, the window regulator (the cable mechanism) or the electric motor is likely failing. We supply workshop-vetted, original Mercedes-Benz rear window motor and regulator assemblies for the 2014–2018 W176 A-Class.

These original units are far more durable than generic aftermarket alternatives, which often use low-quality plastic clips that fail after only a few months of use. Our genuine units ensure the “auto-up/down” function and anti-pinch safety features work exactly as intended.

• Factory-Perfect Operation: Restores the smooth, quiet, and consistent speed of the rear window operation.

• Integrated Safety: Maintains the “anti-pinch” protection feature, which is essential for passenger safety and requires original electronic calibration.

• Condition: Premium workshop-vetted original component; inspected for smooth rail movement, intact cable integrity, and fully functional motor response.

Key Considerations for Window Motor/Regulator Replacement:

• Assembly Type: The motor and regulator are often sold as a combined unit. It is highly recommended to replace the entire assembly even if you think only the motor is at fault, as the cables inside the regulator are usually the actual cause of the “stuck” window.

• Door Control Module: After installing the new motor, the window may not function immediately. It often requires a “normalization” procedure (a simple reset performed by holding the window switch in the full-up position for several seconds) to recalibrate the anti-pinch sensors.

• Water Ingress: If your current motor failed due to water damage (a common issue if the door seal is leaking), inspect the bottom of the door cavity for debris before installing the new motor.

Workshop Pro-Tip: Don’t skip the lubrication. Before you bolt the new regulator into the door frame, apply a small amount of silicone-based grease to the metal tracks where the window carrier slides. This reduces the mechanical load on the new motor, significantly extending the lifespan of the entire assembly and ensuring the window moves effortlessly.
