The windshield usually leaks from one of two places. Either around the entire windshield because the sealer has broken up, or more commonly where the side mirror bolts on. This is is hard to see without a mirror & flash light. But check it before you replace the windshield because if it's the source of the leak, you'll still have a leak even after replacing the windshield.
Good info.
