MTC Ronak 3085 Window Regulator - Front Left

Mercedes-Benz 300SD Front Left Window Regulator

The MTC Ronak 3085 is an electric window regulator for the front left position on 1978-1980 Mercedes-Benz 300SD models. It is specified without a motor, making it a direct replacement for vehicles that need the regulator mechanism only.

Key Features

• Electric window operation type for powered window systems
• Front left fitment for 1978-1980 Mercedes-Benz 300SD
• Motor not included
• OE-style replacement for the original regulator assembly
• Part number 3085 for catalog and fitment verification

Detailed Description

This MTC Ronak window regulator is built for the front left door on Mercedes-Benz 300SD models from 1978 through 1980. As an electric window regulator, it supports powered glass movement in the door assembly, and the no-motor configuration lets you replace the regulator mechanism while retaining the existing motor when serviceable. The 3085 part number is also useful when cross-checking replacement needs against the original application.

This part cross-references Monroe Shocks & Struts (e.g., 116-720-11-46) for the same application.

What It Helps Fix

• Window glass that will not raise or lower smoothly
• Binding, slipping, or uneven window movement
• Broken regulator tracks or worn lifting components
• Power window operation loss caused by a failed regulator mechanism
• Noise or resistance from a damaged front left window assembly

Installation Notes and Tips

Verify the vehicle is a 1978, 1979, or 1980 Mercedes-Benz 300SD with front left application before ordering. Confirm the existing motor condition, since this regulator is supplied without a motor. Compare the original regulator layout and connector style during diagnosis to ensure the replacement matches the door assembly.

Quality Assurance

MTC Ronak replacement parts are cataloged for specific vehicle applications, and part number 3085 is listed for the front left electric window regulator position on the Mercedes-Benz 300SD platform.
