Product Description

TYC 660186 is a front left window motor and regulator assembly for Mercedes-Benz ML-Class SUVs. It combines the gear-style regulator and motor into one complete unit for the driver-side front window, making it a practical replacement when the original mechanism no longer raises or lowers the glass correctly. This part cross-references Mercedes-Benz OE numbers 163 720 11 46 and 163 820 27 42 for the same application.

Use this assembly on 2003-2005 Mercedes-Benz ML350, 2002-2005 Mercedes-Benz ML500, 1998-2003 Mercedes-Benz ML320, 2000-2003 Mercedes-Benz ML55 AMG, and 1999-2001 Mercedes-Benz ML430 front left applications. The TYC 660186 is built with metal and plastic components and is intended for power window systems that require a complete motor-and-regulator replacement.

Common Issues This Part Can Solve

• Window glass will not move up or down from the driver-side switch
• Grinding, slipping, or binding during window operation
• Motor runs but the window does not travel properly
• Regulator cable or gear failure in the front left door
• Intermittent or slow power window movement

Installation Notes

Verify the vehicle year, model, and front left position before installation. Because hardware is not included, reuse or source the required mounting components as needed. No installation instructions are included, so compare the replacement assembly to the original unit and confirm connector and mounting alignment before final assembly.

Quality Assurance

TYC manufactures replacement electrical and body components for automotive applications, and this window motor and regulator assembly is built to match the listed Mercedes-Benz fitments for direct replacement use.
