What Causes the Abnormal Noise When Raising or Lowering Car Windows?

[McAlyssa]

The reasons for abnormal noise when raising or lowering car windows include: 1. Possible issues with the window regulator mechanism, requiring the removal of the door panel at a repair shop for inspection; 2. Aging of the sealing rubber strips beneath the door windows, which increases friction between the rubber and the glass, leading to noise during operation; 3. Dirt accumulation in the window guide rails; 4. Excessive dirt or dust particles in the gap between the glass and sealing strips, causing friction-induced noise; 5. Malfunction of the window motor. Common scenarios involve hardened rubber strips in the window tracks or dirt buildup, hindering smooth window movement or causing it to get stuck. Regularly spraying WD40 into the window tracks for lubrication is essential. For rubber strips, applying a maintenance agent can preserve their flexibility and reduce cracking.
