What Causes the Abnormal Noise When Raising and Lowering Mercedes-Benz Windows?
2 Answers
Introduction to the causes of abnormal noise when raising and lowering Mercedes-Benz windows: Accumulation of dust in the window rubber guide channel: Excessive dirt increases resistance, causing a creaking sound. The solution is to clean the glass guide channel. Prepare a cloth and a chopstick, wet the cloth with water, wrap it around one end of the chopstick, and secure it with a rubber band. Then insert this end into the glass guide channel and slide it back and forth to clean until no more dirt comes out, indicating it is clean. Aging of the rubber in the window glass guide channel: If there is slight hesitation and abnormal noise when raising or lowering the car window, use window lubricant to address the issue. It is easy to use—simply spray it onto the rubber. Loss of window initialization data: This can be resolved by reinitializing the windows. Turn on the ignition switch, hold the switch up to raise the window, and keep holding it for 5 seconds after the glass reaches the top. Then release the switch and immediately press and hold it again to lower the window. After the glass reaches the bottom, wait for more than 3 seconds, then hold the switch up again to raise the window, repeating the process once to complete the initialization.
I also experienced squeaky noises when rolling the windows up and down in my previous Mercedes-Benz, which was really annoying. It's usually caused by dust buildup in the tracks or aging rubber seals. After each rain, dust tends to accumulate more easily inside. You can use a soft brush dipped in soapy water to clean the tracks, then apply some silicone lubricant. If the noise persists, it might be due to worn-out parts in the window regulator mechanism. Mercedes' power windows have quite delicate structures, especially in older models like the E-Class. Don't delay fixing it, otherwise the window might get stuck or fail to roll up, which would be even more troublesome. It's best to check it yourself before long-distance trips. Parking in a garage rather than outdoors helps reduce dust buildup and naturally minimizes noise. If all else fails, I recommend visiting an authorized dealership to have a professional mechanic conduct a thorough inspection. They can also perform overall maintenance to prevent other similar issues like door lock squeaks from occurring.
