What Causes Abnormal Noise When Rolling Car Windows Up and Down?

[LillianLee]

There are several reasons that may cause abnormal noise when rolling car windows up and down: 1. Dirty or obstructed rubber window tracks: Door window rubber tracks tend to accumulate dust, which can create noise during window operation. In this case, first clean the dust from the rubber tracks with water, dry them thoroughly, and then spray some rubber protectant or lubricant on the tracks. This should eliminate the noise. 2. Aged rubber window tracks: Like windshield wipers, door window rubber tracks are constantly exposed to sun and rain, making them prone to aging and losing elasticity. Friction between the window glass and aged rubber tracks will produce noise, and the only solution is to replace the rubber tracks. 3. Dust or debris in the window regulator or a faulty regulator motor: The door window is operated by the window regulator at the bottom. Although the regulator is hidden inside the door, dust can still find its way in. Additionally, the regulator tracks and cables are coated with grease, making them more susceptible to dust accumulation. To resolve this, simply clean off the dust-contaminated grease from the regulator tracks and apply fresh grease to eliminate the noise.
