What Causes the Noise When Rolling Up/Down Car Windows on Rainy Days in a New Car?

There are many reasons for car window noise, such as aging of the window glass sealing rubber strip, debris in the window glass guide rail, loose screws or clips, etc. The specific details are as follows: 1. Aging of the window glass sealing rubber strip: Aging rubber strips are the most likely cause of car window noise. If the noise occurs in a new car, there's no need to replace the rubber strip immediately. Simply purchase a lubricant online, apply it evenly on the rubber strip, and then try rolling the window up and down several times to see if the noise diminishes. 2. Debris in the window glass guide rail: The gaps in the sealing strip of the window slot can easily allow dust and particles to enter during the window rolling process, which may cause vibration and noise in the car window. If dust and particles accumulate more and more, it can damage the lifting motor, leading to noise and even affecting the lifting function. The solution is to use tools to clean the debris in the guide rail.
The new car makes strange noises when rolling up and down the windows on rainy days. This has also happened to me because rainwater mixes with dust and small particles in the air, sticking to the sealing strips at the edges of the windows, causing friction and noise when rolling them up or down. Although the new car looks shiny and beautiful, the rubber parts need some time to break in and fully fit the glass tracks. On rainy days, the higher humidity makes the rubber softer, making it easier to produce squeaking sounds. I suggest not worrying too much, as this is mostly a minor issue. If you hear a creaking sound while driving, you can try wiping the edges of the glass and the outer tracks with a damp cloth to remove debris. If it persists for several days, it's best to take it back to the 4S shop and have them spray some professional window lubricant. Since the car is still under warranty, this service is usually free. Keeping the window edges clean can also prevent minor malfunctions and ensure clear visibility in rainy weather, making driving more comfortable.
It's quite common for new car windows to make strange noises when rolling up or down on rainy days. I've encountered this issue several times. The main reason is rainwater seeping into the window tracks and seals, reducing lubrication and causing metal or plastic parts to squeak when rubbing against each other. Especially with new cars, the factory-applied lubricant is often insufficient, and combined with increased dust during rainy seasons, the friction intensifies. I usually take preventive measures, such as using a soft brush to clean dust from the tracks on sunny days and then spraying some neutral window lubricant. Don't underestimate this issue—neglecting it can accelerate track wear, even causing the windows to operate less smoothly and affecting their response speed. During the break-in period of a new car, paying attention to these details can extend component lifespan. When parking, try to avoid spots under trees to minimize dust accumulation. Safety first—loud window noises can be distracting, so extra caution is needed during rainy days.
