Window Mechanism
Mercedes-Benz Window Mechanisms
M&B Parts supplies aftermarket window mechanisms (window regulators) to fit a range of Mercedes-Benz models. A failed regulator that leaves a window stuck up or down is a common and important repair.
The window regulator raises and lowers the door glass. When it fails, the window may stick, drop, or move unevenly.
How Window Mechanisms Work
The regulator uses a cable or scissor mechanism, often with a motor, to move the glass. Common failures include a snapped cable, a window that drops into the door, or a window that will not move.
Common Signs You Need a Replacement
- A window stuck up or down
