Why is there water under the car seat?

[StNatalie]

The reasons for water under the car seat are as follows: Not closing the car window tightly on rainy days: After getting out of the car, not confirming whether the car window is tightly closed can cause rainwater to drift into various parts of the car from the loosely closed window. Over time, water will drip under the car's cabin. Problems with the drainage outlet: After ruling out human causes, if there is still water dripping under the car's cabin, the car's drainage outlets should be checked. Firstly, the car has four drainage outlets: the front two are for draining the sunroof, and the rear two are for draining water flowing on the car. If there is a problem with the drainage outlets, maintenance is required.
