Hi all, so it's been raining a lot and for a few days I've noticed the sound of water sloshing when I drive--i thought it was the antifreeze bottle I keep in the back until I opened the back side-door, drivers side. The water is inside the door... So I pull on the trim piece at bottom of door and water starts draining out... a lot of water. So anyone seen this before and can tell me what's happening? Thanks.
