Will a damaged outer window trim cause water leakage?
2 Answers
Damage to the outer window trim will not cause water leakage. Reasons why it won't leak: As long as the sealant around the glass is not damaged or aged, the vehicle will not experience water leakage. In fact, car windows do not rely on the outer window trim for waterproofing; they use the sealant inside the glass for waterproofing. The outer window trim only serves a decorative purpose and helps delay the aging of the glass sealant. Maintenance methods for window trim: Avoid using a high-pressure water jet directly on the sealing ring during car washing, as this can deform the seal. Also, promptly clean dust and leaves from drainage holes and grooves to prevent clogging or reduced performance of the sealing ring. Avoid exposing the vehicle to prolonged sunlight in summer and try to park in a garage.
I've been driving for almost twenty years, and if the window seal strip is damaged, it will definitely leak. This thing is like a rubber edge wrapping around the car window—once it cracks or deforms, rainwater can easily seep in. I had this issue with my old Toyota before; after heavy rain, not only was the car floor soaked, but it also grew mold, creating a terrible smell. In severe cases, water even seeped under the seats, nearly affecting the electronic components of the seatbelt buckle. Leaks don’t just ruin the interior; over time, they can cause rust or short circuits. Checking it yourself is easy: feel the seal strip for cracks and test for leaks by spraying water on the window during car washes. Don’t underestimate it—replace the seal strip as soon as possible. You can buy a matching model on Taobao and either DIY or take it to a repair shop; it won’t cost more than a hundred bucks. Prevention involves regular cleaning to avoid dust buildup that accelerates aging, ensuring driving comfort and safety.
