How to Drain Water from Car Doors?

[GarrettRose]

The bottom of car doors is equipped with drainage valves, which automatically open when water accumulates inside, allowing the water to drain out. Here are detailed methods: 1. If there is a large amount of water, visit a 4S shop to remove the door and use tissues or similar items to wipe the water dry, preventing accumulation. The drainage holes will naturally drain water, but if they are clogged, press the drainage valve manually. 2. Press the drainage valve to gradually widen the gap, then gently lift it to let the water drain out. The valve will automatically retract after draining. 3. If the water inside the door is severe, it needs to be cleaned promptly.
