Wet drivers side floor and back of drivers seat floor

Thank you. I thought so but wasn't sure. I appreciate your help!

My entire passenger side was soaked. I took everything out including all seats, trim, and carpet. The leak was coming from a slot low in the A Pillar that hold a plastic trim piece near the passengers right foot. Traced origin to a large grommet on the A Pillar just above the hinge. The grommet was in place but just lost its seal. May want to also check where electrical components run from the A Pillar into the door.
