So I have finally had enough of the leak that was flooding my floor board and passenger seat. I decided to find the source of the issue. I pulled back the a pillar today during the pouring rain and discovered it was coming from the headliner. And to my surprise it was not the drains. There was a leak coming from where the sunroof is placed into the hole of the car itself. So I'm sealing it with a epoxy for a quick fix lol.
