What to Do When the Windshield Leaks into the Cabin?
2 Answers
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.
