Why is there a strange noise when the Mercedes-Benz window is raised or lowered?
2 Answers
It could be an issue with the rubber seal or the window lift motor. It is recommended to have the new car inspected at the dealership. Below is some relevant information about car windows: 1. Introduction: The car window (car-window) is an essential part of the entire vehicle body, designed to meet the needs of interior lighting, ventilation, and visibility for drivers and passengers. 2. Window Names: Depending on the installation position of the glass, car windows include: front and rear windshields, side windows, and door windows. The design, structure, and quality of the windows significantly impact the driver's visibility, passenger comfort, exterior aesthetics, and aerodynamic characteristics.
Having driven Mercedes-Benz cars for many years, I've experienced the squeaky noise when rolling windows up and down, which sounds like sandpaper rubbing against glass. The most common issue is excessive dust or small stones accumulated in the tracks, as window gaps easily collect dirt during daily driving. Over time, the rubber seals can also age and crack, losing elasticity and causing friction noises. I've personally tried cleaning the window tracks: after wiping them clean with a soft brush and cloth, spraying some dedicated window lubricant solved the problem. However, if the noise comes from inside the door, it might indicate worn-out window lift motors or loose track brackets. In such cases, DIY repairs carry risks, and it's better to have professionals remove the door panel to inspect the components. Remember, never ignore strange noises – prolonged neglect may lead to stuck window regulators that can't close the window, risking water leakage during rain. As a car owner, having technicians check the window system during regular maintenance ensures both peace of mind and safety.
