I just bought a 2011 JKU three weeks ago. Shortly after I got it I noticed the passenger side floorboard was wet. It has been raining quite a bit lately so I thought it getting in somehow. I let it dry with the door open and the mat out. We'll it rained again and it was wet again. My neighbor works on cars and he said it might be the heater core leaking. I called the dealer and took it in Thursday. They replaced some seals on the door and said it was good. It hasn't rained in a few days and the floor was wet today. Any thoughts on what might be going on? I'm going to call and take it in.
