What Are the Causes of Car Water Leakage?
2 Answers
Car water leakage can be caused by different locations: 1. Door leakage: aging of window waterproof strips or blockage of door drainage holes; 2. Sunroof leakage: blockage of sunroof drainage holes; 3. Trunk leakage: poor sealing of trunk seals or poor sealing of tail light seals. The methods to deal with car water leakage are: 1. Use dry towels or water scooping tools to clean up the accumulated water in the car; 2. Identify the leakage location and repair it. The effects of car water leakage are: 1. The rubber strips of the sunroof and trunk will mold, and the metal will corrode; 2. Door leakage will damage the door lock and affect the window lifting system.
Car water leaks can be really annoying. Having worked in auto repair for many years, the most common issues I've seen are clogged sunroof drain holes or deteriorated seals. After rain, the car gets damp inside mainly because leaves and dirt block the drainage channels, allowing water to seep in. Another issue is cracked door seals—over time they harden and deform, letting rainwater trickle through the door gaps. If water leaks inside and soaks the floor mats, prolonged exposure can lead to mold, rust, and even damage to the AC system or wiring. Prevention is straightforward: I recommend clearing the sunroof and door drain holes every 2-3 months during car washes—just flush them with a hose and check seals for cracks. This is especially crucial before summer monsoons to avoid turning your car into a mobile reservoir.
