How did the car leak?

The causes of water leakage in the car may be: 1, water leakage caused by aging or fracture of the waterproof strip of the car; 2. There is too much dust and debris in the drain hole of the skylight drain tank, which blocks the drain; 3. The rubber bolt of the bottom plate is embedded in the hole, and the car will leak if the rubber bolt deviates from the hole. After the car has been used for a long time, the waterproof strips at the door and trunk switch may age or even break, and rainwater will flow into the car along these gaps, resulting in water leakage. When it rains, the water drops on the wet umbrella will wet the pedal pad. If it is not dried, it is easy to get moldy, the musty smell is difficult to remove, and sometimes it can cause respiratory diseases. When putting the umbrella into the car, pay attention to spin the water, put it in a plastic bag, and dry the wet pedal pad as soon as possible.
