What is the problem with water on the floor of a sedan?

It may be due to rust perforation in the chassis or water splashing in from the wheels. Below is relevant information about automobiles: 1. Definition of an automobile: According to the latest national standard in China, "Terms and Definitions of Types of Automobiles and Trailers" (GB/T3730.1-2001), an automobile is defined as follows: a non-track vehicle powered by an engine, with four or more wheels, mainly used for transporting people and/or goods; towing vehicles for transporting people and/or goods; or for special purposes. 2. Introduction to domestic automobile brands: Domestic automobile brands include Hongqi, Changan, Great Wall, Chery, Geely, Roewe, BYD, etc.
Recently, there's been water accumulating on the front passenger floor of my car, and it took me a while to figure out why. In summer, when the air conditioning is on, the evaporator generates condensation, which should normally drain out through the undercarriage drain tube. If the drain tube is clogged or detached, the water can backflow into the car. Another common issue is when the sunroof drain holes get blocked by leaves, causing rainwater to flow down the A-pillar and soak the carpet underneath—this needs immediate attention. A friend of mine had his car flooded, and the floor wiring harness rusted completely, costing nearly ten thousand yuan in repairs. My advice is to first remove the floor mats to ventilate and dry the area, then use an air gun to clear the drain holes. If the water has a sweet smell, it's essential to check the coolant reservoir.
