Womala Window Lift Mechanism OE 31253515 Rear Left Door Glass Lift Bracket for Volvo S40 V50

The Rear Left Window Lift Mechanism (Glass Lift Bracket, OE Number: 31253515) is a key component in the power window system of select Volvo models, responsible for guiding and stabilizing the rear left door glass during elevation and lowering.

Constructed from high-strength steel with a corrosion-resistant coating (electrophoretic deposition) and reinforced plastic pulleys, it combines structural rigidity with smooth operation. Unlike generic brackets, this OE part features precision-engineered tracks, mounting points, and cable routing that align perfectly with the door panel and window motor of compatible models.

• Glass Stabilization: Guides the rear left window along a fixed vertical path, preventing lateral movement that could cause the glass to bind, scratch the door frame, or shatter during operation.
• Load Distribution: Bears the weight of the window glass (typically 1.5-2.5 kg) and distributes stress evenly across the lift mechanism, reducing strain on the motor and cables to extend the system's lifespan.
• Smooth Operation: Incorporates low-friction pulleys and lubricated tracks that minimize noise (≤35 dB during movement) and ensure consistent, jerk-free window movement--critical for user comfort.
• Safety Integration: Works with the window motor's anti-pinch sensor by maintaining stable glass positioning, ensuring the system can detect obstructions and reverse direction to prevent injury.

As a direct OE replacement, it installs seamlessly using the vehicle's original hardware, including bolts and clips, ensuring a secure fit that restores full functionality to the rear left window.
