Why is there water inside the car door?

[NathanMarie]

If it does not affect normal use, allowing the water to dry naturally is a good option. You can use a hair dryer to blow dry the wet areas to speed up evaporation. Alternatively, you can directly visit a 4S shop for professional inspection and maintenance to avoid potential issues such as short circuits caused by water ingress. The reasons for water inside the car door are as follows: 1. Severe aging of the door edge waterproof and soundproofing strip: Aging of the waterproof strip usually occurs in older vehicles. This issue is obvious, as you can see the leakage points. Later, simply replace the new waterproof and soundproofing strip. 2. Clogged drainage holes in the door: The door design includes drainage holes at the very bottom. Water entering the door will drain out through these holes. If you notice excessive water accumulation in the door, check whether the drainage holes are clogged and clear them if necessary.
