Master Power Window Switch for Mercedes-Benz

This driver and passenger side master power window switch assembly restores full control of multiple power windows, door locks, and mirror adjustment on select Mercedes-Benz C-Class models such as C300, C350E, and C43, providing a direct plug-and-play replacement for worn or unresponsive factory units.

Overview

The master power window switch is an interior control module that consolidates all window, door lock, and mirror commands into one panel, typically positioned on the driver-side door for easy access. Designed for Mercedes-Benz C-Class sedans, coupes, and cabriolets, including C300, C350E, and C43 variants, this power window switch restores proper one-touch operation and multi-window control for owners dealing with intermittent or failed switch contacts. It is a practical solution for DIY maintainers and independent shops aiming to bring back factory switch functionality without replacing the entire door module.

Good To Know

Q: Will this master power window switch require programming after installation? A: On most Mercedes-Benz C-Class models the switch is plug-and-play, though performing a window normalization procedure by fully cycling each window up and down after installation is often recommended to restore one-touch operation.

Q: Is this switch suitable for both left-hand and right-hand drive configurations? A: This master power window switch is designed for left-hand drive vehicles unless explicitly noted, so matching the part orientation and button layout to your specific cabin configuration is essential for proper fit and function.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
