1995 Saturn SL2 why water is leaking in

Sound's like your a/c drain is clogged up and not draining. In your engine compartment on your firewall down low about in the middle of it you will see a hole get a coat hanger and use that to clean it out make sure the car is parked somewhere you don't mind getting wet there is probably atleast a gallon of water trapped in there. Let me know how it goes.
