I really hope that someone can help me with this! After a heavy rain I noticed a very large puddle on the passenger floorboard. it did not leak from the roof or the windows, I know this b/c my clothes were on the floor and were not wet on top only on bottom. After checking the underside I could not find any obvious areas were the water could have gotten in. I pulled up the carpet and also could not locate a rust hole or anything. The carpet was extremly soaked on the bottom! Please Help, it is starting to smell bad!! Maybe it leaked down the floorboard from under the dash somewhere??
