What is the reason for the floor water in the driver's seat of Hyundai Elantra?

Hello, my friend, there are three reasons for this situation. The first reason is that the heating water tank leaks, the second reason is that the air-conditioning tap water pipe is blocked, and the third reason is that the chassis is flooded. There is a hole under the seat, and the seal is not tight. I hope my answer can help you. Please feel free to contact me if you have any questions.
