Mercedes® Window Regulator, Front Left, Without Motor (With Brose Regulator), 1984-1991 (126)

You're driving along one day, minding your own business while basking in the opulence of your Mercedes and you try to roll down the window only to hear a horrendous clunking, grinding, and snapping sound. Suddenly, your window ceases to raise and lower and is not responding other than the terrible sounds emanating from the door panel. You may have just become a victim of the all too common window regulator failure. The window regulator is just another name for the channel& pulley system that guides the windows path up and down. With time, this system weakens from coagulated grease and dirt build up in the teeth and pulleys of this system causing the power window motor to overheat and fail. Occasionally, the added resistance breaks the critical plastic pieces that keep everything moving smoothly. Fortunately, replacing the window regulator requires a simple tool set and basic automotive knowledge. If you are not mechanically inclined, it helps to have the right part ready for your mechanic. Performance Products knows how important it is to keep your Mercedes-Benz in tip top shape. We have sourced our window regulators form all corners of the world to bring you only the very best in automotive perfection.
