Only happens after it is wet outside. I am thinking there is a hole underneath. Anyone have any ideas?

look underneath? ;)

Lol, duh but if there isn't a hole then where would this becoming from?

Wet Floor
 

I am having the same problem, but mine is on both sides, and it only happens when it rains. Sounds like we got a leek some where, but why just the floor and nowhere else?

it is probably your door seals. they shrink and cause gaps and what not.

remove the seal completely, and then reinstall it starting from the top, with the seam at the bottom. I bet you will have a couple inch gap. you can either fill it with silicon, or just get new seals

I was noseing about under the carpet of my car and found LOTS of water. Funny thing is that the carpet wasn't wet on top. It looks like the underfoam is water proof and not letting the moisture up through the carpet.
I'm sure the water was from the leak in my windshield.

Update there is no holes or rust underneath the bottom side of the car.

weather stripping
 

I am going to order new weather stripping for my car. Does anyone know what size I should order? am getting it from j.c. whitnay, and they have 15 different sizes.

I checked my weather stripping and there is no gaps of any kind. There is one on the passenger side but it doesn't leak over there at all.
