I have a 5 speed 2000 protege. When the A/C is running, water leaks and soaks the entire floor on the passenger side only. I don't know much about cars and don't know what is causing this. I would appriciate any advise on how to address this situation.

 

There is a drain on the blower box, which is under the dash, behind the glove box on that passenger side, that is probably blocked or disconnected. You may want to use a wire to unclog the drain.
