What Causes Water Under the Car Foot Mat?

[Xavier]

Water under the car foot mat may be caused by a leak in a certain part of the vehicle body. It is necessary to locate the source of the leak and repair it, as well as clean up the water under the foot mat. There are many parts of the vehicle body equipped with drainage channels or drain holes, such as doors, the front windshield, sunroof, trunk lid, etc. Here are the specific details: 1. Clogged Drain Holes: During heavy rain, water may enter the car, potentially damaging electronic equipment. It is recommended that owners clean the vehicle's drain holes and drainage channels during regular maintenance. 2. Small Cards Stuck in the Door Window Gap: It is common to see people inserting small cards into the gap of the door window. Owners should remove these cards before raising or lowering the window, otherwise the cards may easily fall into the door. If a card falls into the door, it may clog the door's drain hole, leading to serious malfunctions. 3. Drain Holes at the Bottom of the Door: During heavy rain, some water may enter the door through the gap between the window glass and the door. If the drain holes are clogged, water will accumulate inside the door, which can damage some of the door's electronic components.
