Purpose and Fitment for Mercedes ML W164

The presented regulator has been specifically designed for the rear right window of the Mercedes ML class, generation W164. Its placement on the vehicle is clearly defined, ensuring the part fits factory mounting points and works with the original window guidance mechanism. This precise fit minimizes the risk of play, noise, and uneven window operation during raising and lowering.

Construction and Function of the Window Regulator

The regulator belongs to the Window Regulators and Motors group, responsible for transferring torque from the electric drive to the window's movement within the guides. The design intended for the rear right side ensures:

• stable vertical window guidance,
• even distribution of loads on supporting elements,
• cooperation with the factory window control switch,
• proper operation within the vehicle's typical operating temperature ranges.

This allows the window lifting system to maintain correct geometry, and the mechanism to operate smoothly and predictably in daily use.

Characteristics of a Used Part

The offered regulator is a used part, meaning it comes from a dismantled vehicle and has already been in use. This type of part is a good solution when you want to maintain the original manufacturer's specifications while optimizing repair costs. A used regulator allows you to restore full functionality to the rear right window without the need for electrical system modifications or mounting adjustments.

Benefits of Using an Original Regulator

Using an original window regulator for the Mercedes ML W164 offers a number of practical benefits:

• Factory Fitment – compatibility with the door structure and window guide, no modifications required.
• Electrical System Compatibility – designed to work with the original window controls and safety features.
• Stable Mechanism Operation – proper window guidance reduces the risk of jamming and uneven movement.
• Economical Repair – a used part lowers the cost while maintaining parameters close to factory specifications.

How to Choose the Right Window Regulator

When selecting a window regulator for the Mercedes ML W164, it is crucial to pay attention to the installation side (rear, right) and compatibility with the manufacturer's markings. If in doubt, it is advisable to compare the shape and mounting points with the part removed from the vehicle or seek assistance in verification using vehicle data. This approach minimizes the risk of purchasing a part with a different mounting purpose.
