notice few months ago it damp and didn't do much to investigate.We've been having lots of rain the last month and its just soaked now with some standing water. Its just the drivers side and most generally on the floor/horizontal rather than the vertical parts. Any thoughts??????? Where are all the various drain hole and drain tubes that could be the issue. I do have a sunroof I never use but if leaking there woudnt seem it would just be driver side floorboard, Read somewhere maybe heater core????????????, if there was an issue there would I not be getting poor heat?????---getting good heat. Read somewhere bout AC evaporator but obviously not running AC the last 3 months. Appreciate any suggestions or thoughts
