What Causes Water Under the Car Carpet?
2 Answers
Water under the car carpet is usually caused by air conditioning leaks. Here are detailed explanations about carpet water ingress: 1. Treatment Methods: If the carpet is only slightly wet, you can use a cleaning agent to remove dust and dirty water from the carpet; for severe water ingress, it's necessary to remove the seats and lift the floor covering for thorough cleaning. 2. Precautions: Avoid completely soaking the carpet in water for scrubbing, as this can damage the adhesive between different material layers inside the carpet and may result in prolonged drying time that affects usage effectiveness and causes interior humidity.
If you find water under the car carpet, there could be several reasons. The most common is aging seals on the sunroof or windows leaking, allowing rainwater to seep through gaps into the carpet. A clogged air conditioning system drain pipe can also cause condensation water to flow under the carpet, especially during frequent AC use in summer. Improper car washing or parking in low-lying areas may allow water to backflow through door drain holes. Internal causes include a cracked water tank or accidental spills that weren’t dried promptly. Prolonged water accumulation can lead to mold, rusting of metal chassis components, and unpleasant odors. It’s advisable to first identify the leak source—clean with a dry cloth and ventilate with windows open for a few days to observe. If the issue persists, visit a professional shop to inspect seals and drainage systems to prevent long-term damage to vehicle electronics. Regular maintenance checks of these areas are crucial to avoid minor issues turning into costly repairs.
