Where is the water on the car floor leaking from?

[DeJuniper]

Water on the car floor is caused by two reasons: 1. Water produced during the operation of the vehicle's air conditioning system, which flows into the car due to a blocked air conditioning drain pipe. 2. External water accumulation entering the vehicle due to clogged sunroof drain pipes. In such cases, the affected parts need to be disassembled, dried, and treated. Additional information about water on the floor: 1. Impact: If left untreated for a long time, water on the floor can cause rusting, severe cases may lead to rotting, affect the vehicle's speed limiter in the chassis area, impair normal driving operation, and even create safety hazards. Therefore, timely treatment is essential. 2. How to protect the vehicle floor: The vehicle floor can be protected using full-coverage floor mats, which effectively safeguard the floor. Especially during seasonal use, it's necessary to regularly check the sunroof drain outlets, air conditioning drain outlets, and door drain holes to prevent water ingress caused by blockages.
