What Causes Car Doors to Leak Water on Rainy Days?
2 Answers
Car doors leaking water on rainy days are usually caused by two reasons: water entering while the vehicle is in motion or water seeping in when the vehicle is parked. There are gaps on the car body and doors, making it inevitable for rainwater to penetrate the doors during rainy weather, leading to water leakage. Introduction: Car doors (car-door) provide access for drivers and passengers to enter and exit the vehicle, isolate external interference, mitigate side impacts to a certain extent, and protect occupants. The aesthetics of a car are also related to the design of its doors. Standards for Good Car Doors: The quality of car doors is mainly reflected in their anti-collision performance, sealing performance, ease of opening and closing, and of course, other functional indicators. Anti-collision performance is particularly important because, during a side impact, the buffer distance is very short, making it easy for passengers inside the car to get injured.
I've been driving for decades and have encountered many issues with water leaking into the car doors during rain. The main reason is that the rubber seals around the doors age over time, becoming hard or cracked, allowing rainwater to seep through the gaps. The drainage holes at the bottom of the doors can easily get clogged with dirt, leaves, or debris, preventing water from draining and causing it to seep in through the door sills. If the window seals become loose, they can also leak, especially when the door is closed but the seal isn't tight. If the car body has been in an accident, even slight deformation of the door frame can make it more prone to leaks. As the car ages, these components wear out severely, and when water gets in, the floor and floor mats become damp. Over time, this not only leads to rust but also produces a musty smell, which affects the driving experience. I recommend checking the drainage holes immediately after rain and using a thin wire to clean them out, which can significantly reduce the risk of water leakage.
