I have a 1997 Dodge Neon Spot. When it rains, water keeps getting in it. It's only getting on the floorboards, and the trunk where the spare tire goes. After a heavy rain the other day, I had 4 inches of water in my trunk where the spare tire goes, about an inch and a half of water on the back floorboards, and the front floorboards had a bit of water also The seats and the rest of the interior are all dry. The rest of the trunk around where the spare tire goes is dry also. Does anyone know what could be causing this?Thank you.
