I have recently noticed that on my rear driver's side floorboard it gets soaked when it rains.The windows are not leaking the roof is always dry the door seals are still good. The seats are never wet. Nothing is ever wet except the floor. It is also soaked before I drive it anywhere. Where is this water coming from?! Has anyone else had this problem? Any suggestions? I would like to figure this out before it causes rust mold or mildew problems of course. Any input is greatly appreciated! Thanks!!
