How to remove and refit of the front door window regulator assembly on Mercedes-Benz 190E?

To remove the door inner trim panel, first open the window until the guide member of the regulator guide rail is accessible through the aperture in the top center of the door panel. Support the window in this position using either a wooden wedge between the window and the door or masking tape over the top of the door frame and onto the glass on both the inside and outside. For cars with electric windows, disconnect the wiring plug connection and release the two wires for the window lift motor. Next, remove the locking clip that secures the window glass to the guide member of the regulator guide rail, then undo the two regulator retaining bolts for manual windows or the three regulator nuts for electric windows. After that, undo the regulator guide rail lower retaining bolt and swivel the regulator rearwards to release the guide member from the channel at the bottom of the window glass. For electric windows, remove the motor wiring cable connector from the door panel, and then manipulate the regulator assembly out of the large aperture in the door panel. The refitting process follows the reverse order of removal.

Mercedes-Benz Window Regulator allows for smooth electric or manual operation of the door glass to allow occupants to have quick control over fresh air and clear sightlines in each ride. The wider Mercedes-Benz range is known for combining German engineering with stylish design, cutting-edge infotainment such as MBUX, efficient energy recovery in electrified drivetrains and the upcoming MB.OS platform, which combines driver assist features with artificial intelligence to create a connected, safer and smarter driving experience. Focusing on athletic handling, refined cabins and dependable durability that have defined the brand since its 1926 beginnings, drivers enjoy the company's continuous push to keep journeys comfortable and intuitive with digital.

Mercedes-Benz Window Regulator Parts and Q&A

Window Regulator
201-720-05-46
Q: How to remove and refit of the front door window regulator assembly on Mercedes-Benz 190E?
A:
To remove the door inner trim panel, first open the window until the guide member of the regulator guide rail is accessible through the aperture in the top center of the door panel. Support the window in this position using either a wooden wedge between the window and the door or masking tape over the top of the door frame and onto the glass on both the inside and outside. For cars with electric windows, disconnect the wiring plug connection and release the two wires for the window lift motor. Next, remove the locking clip that secures the window glass to the guide member of the regulator guide rail, then undo the two regulator retaining bolts for manual windows or the three regulator nuts for electric windows. After that, undo the regulator guide rail lower retaining bolt and swivel the regulator rearwards to release the guide member from the channel at the bottom of the window glass. For electric windows, remove the motor wiring cable connector from the door panel, and then manipulate the regulator assembly out of the large aperture in the door panel. The refitting process follows the reverse order of removal.

Q: How to remove and install a window regulator and motor assembly on Mercedes-Benz 300TD?
A:
Unscrew the door inner trim panel and plastic sheet and bring the window down. Disconnect the Negative cable at the battery and engineer it out of the way to avoid inadvertent contact with the negative terminal which would permit current back into the vehicle circuit breaker. Unscrew the bolts that hold the lifting rail onto the glass channel, and lift the window and hold it by a block of wood. Label the points where the wiring connectors are to be connected so that they can be reconnected to the terminals. On the back door, loosen the screws forming the channel of the back window and separate them forward. Unscrew regulator and motor assembly attachment bolts and nuts by unscrewing to extract through the opening of the regulator and motor. To install, assemble as before in last step of this procedure and on lower travel of the window make any amendment by requires of lifting the bolt and placing the stop pad on the regulator arm.
