What causes water under the driver's feet?

[LaAngelina]

Water under the floor mat in the driver's compartment may be caused by leaks in certain parts of the vehicle body. It's essential to locate the source of the leak and repair it, as well as thoroughly dry the water under the floor mat. Many parts of the vehicle body have drainage channels or drain holes, such as doors, the front windshield, sunroof, and trunk lid. More details are as follows: Explanation 1: If drain holes are blocked, heavy rain can cause water to enter the vehicle, potentially damaging electronic components. It is recommended that owners regularly clean the vehicle's drain holes and drainage channels during maintenance. Explanation 2: It's common to see people inserting small cards into the gaps of door windows. Owners should always remove these cards before operating the window, as the cards can easily fall into the door when the window is raised or lowered. If a card falls inside the door, it may block the door's drain hole, leading to serious malfunctions.
