What Causes the Noise When Tesla Window Glass Goes Up and Down?

[JuniperRose]

Tesla window glass making noise when going up and down may be due to dust accumulation in the window rubber guide channel or rubber aging. Here are the detailed explanations: 1. Dust accumulation in window rubber guide channel: Generally, the noise during window glass movement is caused by dust accumulation in the rubber guide channel. The dirt increases resistance, resulting in creaking sounds. The solution is to clean the glass guide channel. If you have dashboard wax for interior maintenance, spraying a little into the glass guide channel will yield better results by reducing resistance, thus eliminating noise during window operation. 2. Aging of window glass rubber guide channel: Another reason could be the aging of the rubber in the window glass guide channel, causing slight hesitation and noise during window movement. Use window lubricant by spraying it on the rubber. This serves two purposes: lubrication and maintaining rubber flexibility to prevent drying and cracking.

I've been driving a Tesla Model 3 for a while now, and I've also encountered the issue of strange noises when rolling the windows up and down. At first, I thought it was dust stuck in the tracks, but later I realized it could also be friction caused by aging rubber seals. I tried cleaning it myself: using a soft brush to sweep away dust particles in the window gaps, then spraying some window-specific lubricant. If it's a seal issue, applying some silicone-based protective oil can significantly reduce the noise. However, if the noise persists, you should be cautious—it might be due to worn-out motor bearings or a deformed drive belt. Tesla's door panel design is quite complex, and sometimes bugs in the electronic control system can also cause mechanical abnormalities. I recommend not delaying and getting it checked at a 4S shop early on. Otherwise, it’s not just annoying but could also accelerate part wear and affect the safety of the window operation. Regular cleaning during maintenance can save a lot of hassle.

Tesla window rattling often stems from track dust accumulation or mechanical faults. Dirty or deformed guide rails can produce harsh friction sounds; lack of lubrication in motor gears or loose bearings may cause rattling noises; hardened sealing strips also contribute to the noise. Before diagnosis, first locate the sound source: operate the window in a quiet environment to identify the position. Simple solutions include cleaning the track with anhydrous ethanol or applying lubricant spray; stubborn cases may require part replacement. Tesla's electronic modules sometimes interfere due to software glitches—try an OTA update or reboot. Most issues are physical factors, easily identified with professional tools.

When encountering window rattling, I usually maintain it more frequently to prevent issues. Tesla windows are prone to dust accumulation and sticking noises, so I wipe the tracks and edges with a soft cloth weekly. I apply rubber and plastic protectant to the seals to prevent aging and cracking. After raising or lowering the windows on rainy days, I dry them to avoid corrosion. If the noise gets louder, I avoid forcing the window to prevent motor damage. Prevention is better than repair—these small habits can extend the system's lifespan, reduce the chance of rattling, ensure safer driving, and save the hassle of repairs.
