2003 Chevrolet Impala Question: How to repair a windshield that leaks when it rains?
remove and reseal but make sure you ck steel seam where windshield seal for corrision - globalhelper
I seriously doubt that a windshield repair would cause a water leak three years later. If you had the windshield replaced or even if it is the original glass then the urethane seal between the windshield and the windshield opening has failed. You need to have the windshield resealed. To do this properly the glass needs to come out, check for rust or rot, repair as needed and re-install the windshield with the correct urethane NOT silicone. Also, you didn’t mention if your car has a sunroof or not which can cause leaks that sometimes get misdiagnosed as windshield leaks. - Herb Ackside
