Most likely its the windshield...most other things leak right away,not years later...if your sure its rain waTER AND NOT A/C

if you are sure it is just water, then it might be coming in from the door seal above the window. I doubt that it is the windshield, but I could be wrong. You want to make sure your heater core isn't leaking. I ran through 3 of them on my 91.
