What to Do If the Windshield Leaks?

Should remove the windshield and clean off the original sealing material (sealant). When reinstalling the windshield, pay attention to waterproofing if using new sealant. Do not drive until the sealant is completely dry.
I've been driving for many years, and windshield leaks are a common issue, usually caused by aging sealant strips or clogged drainage holes. You can first inspect the rubber sealing strips around the edges of the glass yourself to see if there are any cracks or detached areas, and temporarily seal them with transparent tape to stop the water. The drainage holes are located at the bottom of the windshield; carefully unclog them with thin wire or a toothpick and remove any leaves or dirt. I've tried this method before, and it worked quite well, reducing leaks by 70-80%. However, for a permanent fix, especially if the car body is already rusty, you'll need to visit a professional repair shop to reseal or replace the strips. Don't delay, as water seeping into the electronic equipment under the dashboard can double the repair costs. For regular maintenance, wiping the glass seals with a soft cloth can prevent aging. Remember, if a leak causes slippage while driving, it's dangerous—pull over immediately and turn on your hazard lights.
I think a leaking windshield is a safety hazard, especially during rainy downhill drives when visibility is compromised. Leaks can be caused by cracked installation adhesive or clogged drainage systems, and water seeping into the car can wet circuit boards, leading to short circuits or rust. Addressing this issue requires caution: first, check for gaps around the edges of the glass and gently tap to see if it's loose; clean the drainage holes under the air conditioner using a pump or vacuum to remove debris. Minor issues can be handled DIY, but major leaks—like internal dripping—require stopping and seeking a professional technician. They have the right tools to quickly locate the leak and reseal it. I’ve even seen cases where prolonged leaks caused body corrosion, with repair costs easily reaching thousands. For prevention, spray water on the seals after washing the car—if no water drips, it’s fine. If you notice a leak, address it immediately—don’t push through on the highway.
