How to Deal with Water Under the Car Cabin Floor Mat?
3 Answers
Go to a car wash shop, take out the floor mat, and use a vacuum cleaner to remove most of the water. Use dry towels alternately placed under the floor mat to absorb water. Continue until all the water is absorbed, ensuring the area under the cabin floor mat is completely dry. Visit a repair shop to use high-pressure air to blow through the pipes and clear any blockages. It is recommended to regularly check and clean the drainage pipes under the windshield to prevent clogging. The issue may be caused by a leak in a certain part of the vehicle body. Locate the leaking area and repair it. There are many drainage channels or holes in different parts of the vehicle body.
Last time I encountered water under the driver's side floor mat, emergency handling was crucial. The first step is to quickly remove the floor mat and use a dry towel or old clothes to soak up the water—don't let it sit. Next, find a well-ventilated area to open the car doors and let it air dry, placing a fan to speed up the drying process. The water might come from a clogged sunroof drain or aged door seals allowing rainwater to seep in. If left unaddressed, the water can seep into the carpet, rust the floorboard, or cause mold and unpleasant odors, affecting health. In severe cases, if water enters the electrical system, it could cause a short circuit. After drying, it's advisable to drive to a nearby repair shop for a thorough leak inspection to prevent minor issues from escalating. When parking, avoid low-lying areas, and check under the floor mats after rain.
When I find water in the cabin, I diagnose it step by step myself. First, take off my shoes and get in the car to carefully check the water location—is it only on the driver's side or throughout the entire car? Feel the carpet's moisture and flow direction to determine the source. Common causes include clogged sunroof drain tubes or broken air conditioning condensate drain pipes leaking. Try simple cleaning: use a wire to clear the small holes in the sunroof corners or inspect the air conditioning evaporator's drain outlet. Remember to wear gloves during the process to avoid dirty water contamination, and ventilate by opening windows after absorbing the water. If you can't fix it yourself, the water may corrode interior electrical wiring harnesses—take the time to thoroughly eliminate the hazard. Doing some maintenance on a sunny weekend can save a lot of money; don't wait until problems arise to regret it.
