How to Repair Water Leakage at the Upper Ends of the Windshield?

Should remove the windshield, clean the original sealing material (sealant), and repair the damaged parts. When reinstalling the windshield, pay attention to waterproofing when using new sealant. Do not drive the car until the sealant is completely dry. You can clean the edges of the glass thoroughly and use an air gun to blow them dry. After ensuring the area is completely dry, apply glass sealant yourself. If the issue still persists, the only solution is to replace the glass. When replacing, remind to apply more sealant.

Last week, I encountered the same issue. After washing the car, I noticed water dripping from both sides at the top of the windshield, soaking the seats. I tried inspecting it myself and found that the black sealing strip around the glass edge might have aged, hardened, or cracked, allowing water to seep through the gaps. I dried it with a towel and cleaned off the dirt with a small brush, but water still leaked in. Later, I took it to a friend's auto repair shop, and he said the windshield wasn't sealed properly during installation or the adhesive had failed. They used professional tools to reapply sealant and pressed the strip tightly—now there's no more leakage. I recommend addressing this quickly, as water entering the dashboard could short-circuit the wiring. Check this area after car washes or rain, and fixing it early will save you money.
