Mercedes Power Window Motor - Genuine Mercedes 4637201346

Product Information

A window motor is an electric motor inside a vehicle’s door that powers the window regulator, allowing you to raise or lower a power window at the push of a switch.

It works by receiving electrical current from the window switch, which then drives gears that move the regulator arms or cables, moving the glass up or down. Window motors are usually paired with the regulator in a single assembly but can also be replaced separately in some vehicles.

• Window Doesn’t Move at All: No sound or movement when pressing the switch, even though the fuse and wiring are good.
• Slow or Jerky Window Movement: The motor is losing strength, causing the glass to move sluggishly or unevenly.
• Intermittent Operation: Works sometimes but not always, often due to worn brushes or internal motor issues.

About Genuine Mercedes

The original parts used by Mercedes Benz to build your car are available as replacement parts under the “Genuine Mercedes Benz” brand. Manufactured under the direction of Mercedes Benz, expect excellent quality and a premium price since these parts are exclusively available through the Mercedes Benz Dealership network.

You may not realize this, but the parts that make up your Mercedes-Benz are not necessarily manufactured by Mercedes-Benz. No cause for concern, as Mercedes-Benz designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for Mercedes-Benz for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine Mercedes-Benz parts box and find an OEM branded part inside, simply with the addition of a Mercedes-Benz logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
