1992 Chevy Corsica Water Leak

Is it leaking while your a/c is on? If thats the case it is supposed to. Thats condensation build up

Do you know where its leaking from? And are you sure its not coolant?

It sounds like the drainage system in your car is clogged with leaves or debris, forcing it to drain at a different location. You know the channels along the doors and the windshield cowel just below the windshield, well if leaves and other things are clogging it, rain and water will find another way to drain try to vacuum all of the leaves and debris from the doors and cowel and see what happens
