Why does the car window make noise when rolling up or down in the rain?

Window noise may be caused by dust in the rubber guide channel or aging of the window rubber. The specific reasons for the noise during window operation are as follows: 1. Accumulation of dust in the window rubber guide channel: If noise occurs during window operation, it is likely due to a large amount of dust accumulated in the rubber guide channel. This increases resistance during movement. Moreover, if the dust contains some particles, it will produce noise. In this case, simply wrap a wet cloth around one end of a chopstick, secure it with a rubber band, and insert it into the glass guide channel, sliding back and forth to clean. 2. Aging of the window rubber: Besides dust accumulation, aging of the window rubber can also cause noise during window operation. Simply apply lubricant to the rubber. Spraying it on the rubber not only lubricates but also maintains the rubber's flexibility, reducing the likelihood of cracking.

Having driven for over a decade, I've encountered this situation many times. When it rains, the car windows make noise while rolling up and down. The most common reason is rainwater seeping into the window tracks. When the tracks get wet, the friction coefficient increases, enhancing the friction between the glass and metal or rubber, resulting in squeaky sounds. Rainwater also tends to carry dust or fine sand particles, which accumulate in the track gaps, making the operation less smooth and the noise more piercing. Aging rubber seals are another major factor—they expand, deform, or harden after getting wet, creating uneven contact surfaces and increasing friction during operation. The solution is actually simple. I regularly clean the track dust with a soft cloth and apply silicone-based lubricant to reduce friction, avoiding frequent window operation on rainy days. If neglected for long, the window motor might overload and get damaged, leading to costlier repairs. Developing a habit of checking the seals monthly can significantly reduce such minor annoyances.

I usually drive commercial vehicles for long distances and place great importance on vehicle maintenance and safety. The noise when rolling windows up and down in the rain is mostly caused by rainwater entering the tracks, altering the friction characteristics. Moisture makes the contact surface between the track and glass sticky or wrinkled, naturally producing noise. Rainwater mixed with road dirt, such as dust or sediment deposits, can cause track blockage or increased wear. If the rubber sealing strips age, they may deform or crack when soaked by rain, increasing the resistance when rolling the windows. For prevention, I always use a blower or dry cloth to dry the track area when washing the car to keep it dry and clean. Before the rainy seasons in summer and autumn, I spray waterproofing agents for protection. Timely action is key; otherwise, continuous use can worsen component damage and affect driving visibility in the rain. I always inspect and repair immediately upon noticing any abnormal noise.

I often encounter this issue when driving my kids to and from school. The windows make noise when rolling up and down in the rain, mainly because rainwater wets the tracks, increasing friction and making the glass harder to slide, which causes the noise. Rainwater also brings in dirt like sand, making the tracks dirty and the friction noisier. Old rubber seals that no longer provide a tight fit can deform when wet, leading to more squeaks. My simple solution is to clean the tracks and add some lubricant, plus I avoid frequently opening and closing the windows when it's raining. Regular maintenance is crucial; otherwise, the windows might get stuck.

As a family car owner, I often drive with my family. The windows make noise when rolling up or down on rainy days, which is caused by rainwater seeping into the tracks, increasing friction or accumulating impurities and dirt, making the glass slide less smoothly and producing squeaking sounds. The aging weatherstrips expand and contract after absorbing water, becoming loose when in contact with the glass, creating pulling noises during operation. For solutions, I make it a habit to clean the track dust with a damp cloth every month and operate the windows slowly on rainy days to avoid impact. Given the high frequency of family car use, it's recommended to check the condition of the weatherstrips every six months and replace them in time. Fix small issues promptly to prevent safety hazards and maintain driving comfort.

I'm quite interested in automotive mechanics. The common issue of squeaky car windows during rain occurs because moisture alters the friction characteristics of the tracks. Water changes the stickiness or slipperiness of metal or rubber contact surfaces, creating additional friction noises. Rainwater may also introduce micro-dust and other impurities that wear down the tracks, while aged sealing strips deform after rain exposure, causing gap noises. Additionally, dampened motors may produce slight abnormal sounds. For prevention, I maintain clean and dry tracks and apply specialized silicone lubricant grease. I replace aged components promptly and operate windows more slowly on rainy days to reduce friction. These minor maintenance practices significantly enhance window durability and quiet operation.
