It may be due to issues such as loose screws in the window regulator or the window regulator being stuck. Below is relevant information: 1. Introduction: The car window is an essential part of the entire vehicle body, designed to meet the needs of interior lighting, ventilation, and visibility for drivers and passengers. Car windows are categorized based on the installation position of the glass: front and rear windshields, side windows, and door windows. The design, structure, and quality of the windows significantly impact the driver's visibility, passenger comfort, aesthetic appearance, and aerodynamic characteristics. 2. Structure: Car windows are typically curved and sealed, with rubber sealing strips connecting the window frame and the glass. The sealing strips serve to seal and cushion, preventing damage to the windshield glass when the window frame deforms due to stress on the vehicle body.

I've encountered many situations where the car window won't open after rain, mainly because rainwater seeps into the window tracks. The tracks are made of metal and prone to rusting. Additionally, with high humidity during rainy days, the dust and dirt in the tracks mix with water to form a sticky paste that jams the glass, making it immovable. Moreover, the aging rubber seals along the window edges absorb rainwater, swell up, and clamp too tightly, which can also cause the window to get stuck. During car repairs, I've noticed this issue is common in older vehicles or cars parked outdoors. Forcing the window open can easily damage the lift motor, leading to bigger problems. Prevention is quite simple: try to park the car in a garage or use a waterproof car cover during rainy days. Afterward, wait for things to dry before attempting to open the window. If it still doesn't work, take it to a repair shop to clean the tracks and apply some lubricant—this usually solves the problem. Regular maintenance checks on these areas can help avoid trouble during the rainy season.

I've driven several cars and noticed this issue always occurs during the rainy season. Rainwater may seep into the switches or circuits through door gaps, causing short circuits. The system then activates self-protection by cutting off power, making the windows inoperable. Circuits and relays are the most sensitive components - just a little water can paralyze them, much like how a water-damaged phone malfunctions. I recommend first checking the fuse box to see if the corresponding window fuse has blown, and try replacing it yourself. Additionally, parking in covered areas or using an umbrella to shield the windows can prevent problems before they occur. I once encountered an emergency situation on the road where the windows wouldn't open - I had to drive slowly with the AC on for ventilation until I could get professional diagnostics that identified the issue. Don't delay electronic system maintenance; perform regular tests to ensure proper operation during rainy conditions.

I personally experienced this issue where the car window got completely stuck after being left out in heavy rain. It was likely due to the aging window seals absorbing water and swelling excessively, combined with debris in the window tracks expanding when wet, jamming the window shut. The solution was to visit a repair shop to replace the seals, which wasn't expensive. They also taught me to clean the window tracks with a soft cloth and apply lubricant as a preventive measure. If the window switch gets damp, it's best to let it dry for a few days without forcing operation. The simplest way to avoid this hassle is to park the car in a sheltered spot and use the air conditioning to dehumidify during rainy weather.

From a safety perspective, this is extremely dangerous. I've emphasized multiple times that when it rains, fogging inside the car or the need to urgently open windows for ventilation can lead to major issues if the windows won't open. The main causes are water damage to the tracks or switch circuits, leading to mechanical jamming or signal interruption. Avoid forcing them during rain to prevent further damage. I recommend parking in dry areas like garages daily and regularly cleaning the door and window systems. Installing additional waterproof covers can also prevent rainwater intrusion, potentially saving lives in critical moments and ensuring worry-free driving.
