What Causes the Squeaking Sound When Rolling Car Windows Up and Down?
2 Answers
The reasons for squeaking sounds when rolling car windows up and down: 1. Aging of the window seal strips - As the seal strips age, the friction increases, leading to abnormal noises. This phenomenon becomes more noticeable in summer because aged seal strips expand more significantly under sun exposure, resulting in greater friction and more severe squeaking. 2. Dirt accumulation in the gap between the window glass and seal strips - Particles in the dust rubbing against the glass can also produce squeaking sounds. 3. Dirty window guide rails. 4. Malfunction of the window regulator motor. To address this, roll up the window and rinse the gap between the glass and seal strips with water, then dry it and roll down the window. Next, use an old bank card or similar card wrapped with a damp cloth to repeatedly clean the seal strip gap. After drying, spray some lubricant.
After years of driving, squeaking sounds during window operation are quite common, often due to insufficient lubrication in the window tracks. Dry friction between metal components produces noise, especially in dry weather or winter. Additionally, aging or deformed rubber seals can cause friction with the glass, leading to unusual sounds. I've also noticed that accumulated dust or small stones in the door slots can exacerbate the noise when raising the window. Ignoring these issues may accelerate wear on the window regulator, eventually causing the glass to jam. Personally, I clean the tracks monthly and apply silicone-based spray lubricant—quick and easy. Regular maintenance can extend lifespan, so I recommend making it a habit.
