Water leak windshield? Wipers?

So I left my car out in the rain last week and I came home and noticed that the floor on both passenger and driver sides was soaked. I know that there's a leak in the top part on winsheild so I have to fix that but my question is Does the trim help seal the front windshield at all? Could my floor being soaked be from the wiper motor cuz I know that those are known for leaking.

thanks in advance Dom.
It a 1975 dodge dart sport if that helps at all.
