Carefully remove the windshield, clean off the original sealing material, and repair any damaged areas. Thoroughly clean the upper edge of the glass and sand down the leaking area, then dry it with an air gun. After ensuring the area is completely dry, apply black waterproof glass sealant. Reinstall the windshield using new sealant, paying attention to waterproofing. Use transparent tape to secure the edges of the windshield for stabilization, and remove the tape after 12 hours.

A few days ago, my neighbor's car had the same issue—water leaked through the windshield, flooding the cabin and giving him quite a headache. Generally, aging seal strips are a common cause, especially for older cars after several years of use. Alternatively, improper windshield installation can lead to leaks during rain. I suggest checking around the seal strips on a dry day first to see if there are any looseness or cracks. For a temporary fix, use waterproof tape to seal the leak, but don't delay too long, as accumulated water can cause mold in the carpet or short-circuit the electrical system. When cleaning, use towels to soak up the water and keep windows open for ventilation to prevent moisture. I recommend visiting a professional auto repair shop as soon as possible for a proper resealing—it's not expensive. Also, pay extra attention to the edges of the windshield during car washes to catch and prevent issues early.

Once when I was driving in heavy rain, water suddenly seeped through the windshield, soaking the floor on the driver's side. After some troubleshooting, I found that the seal under the wiper blade had cracked. I cleaned up the accumulated water myself, used a water spray test to locate the leak, and then ordered a rubber strip patch online as a temporary fix. This experience taught me that leaks can be caused by worn seals or improper installation, and water entering the cabin not only dirties the interior but also risks corroding wiring. It's important to dry the floor promptly to prevent electrical damage. If DIY doesn't work, find a reliable repair shop to replace the seal. For prevention, regularly clean the edges of the windshield to prevent dust buildup.

When water leaks into the car through the windshield, safety concerns immediately come to mind, as water seepage could short-circuit the dashboard wiring or cause unpleasant odors. Most of the time, this is due to aging seals or a loose windshield. First, park the car and remove any standing water to prevent slipping hazards. Use a cloth to soak up the water and turn on the heater to dehumidify. Check for leaks around the edges of the windshield, using a small mirror to inspect for cracks. Long-term neglect can damage carpets and wiring, leading to higher repair costs. Don’t try to cut corners by applying sealant haphazardly—getting professional repairs promptly is the most reliable solution. These simple steps ensure safety.
