If the amount of water entering the cabin is very small and the wetted area is minimal, you can wipe the water stains clean yourself, roll down the windows, and if possible, open all the doors to dry the interior in sunlight. Additionally, place some desiccants inside the car. If the amount of water entering is substantial, it is necessary to visit a nearby repair shop or 4S dealership for disassembly and drying of the removed components. Additional Information: 1. Causes of Floor Water Ingress: The air conditioning drain pipe may have detached, directing condensate water to the front driver's seat; the floor drain opening, originally covered with a cap or rubber plug, may have fallen off, allowing water to splash onto the floor while driving; the door seals may not be tight, frequently letting water in; there could be holes or missed weld points in the front bulkhead of the cabin, causing leaks during car washes or heavy rain. 2. Precautions: It is important to note that if the damage caused by water ingress into the cabin is significant, it is best to immediately contact your auto insurance provider. Clearly explain the cause of the water ingress and the extent of the damage to the insurance company's customer service representative, and inquire whether a claim can be filed. Under unclear circumstances, never start the engine, as this may result in the claim being denied.
