Why is there abnormal noise when the car window is raised or lowered?
2 Answers
The reasons for abnormal noise when the car window is raised or lowered are: 1. Excessive dirt or foreign objects in the window glass guide channel; 2. Aging of the window glass rubber or accumulation of dust; 3. Faulty components of the window lifting mechanism. The solutions to eliminate the abnormal noise are: 1. Clean the guide channel by sliding a wet cloth fixed to a chopstick back and forth; 2. Apply lubricant to the rubber to maintain its flexibility and reduce cracking; 3. Replace the window regulator assembly. The function of the car window is to meet the needs of interior lighting, ventilation, and the visibility of the driver and passengers. Depending on the installation position, car windows can be classified into front windshields, rear windshields, side windows, and door windows.
I've been driving for almost twenty years, and abnormal noises during window operation are a common issue. In most cases, it's due to accumulated dust or small stones in the window tracks, causing friction sounds when moving up and down. Another possibility is aging and hardened rubber seals, leading to squeaky noises as the glass slides. DIY solutions are quite simple: clean debris from the tracks with a damp cloth or soft brush, then apply some window lubricant spray to silence the noise. However, if the sound is a harsh metal-on-metal scraping, it might indicate worn-out cables or gear issues in the window regulator, requiring a visit to the repair shop. Ignoring it can accelerate seal damage, risking water leakage into the car during rain. Regular maintenance, including track cleaning, extends lifespan and prevents minor issues from escalating into major repairs.
