Ok. I had a similar post a while ago. Looked at all the others about leaks in the floor. When it rains i get a leak in the REAR drivers side floor. Last time i was thinking that it was the sun roof so i blew out the lines. Well i got deployed so i never found out if i fixed it or not. Right before i deployed for the second time as i was putting my car in a storage i noticed water there again. My question is..is what else could be causing the leak in the Rear passenger floor and only there?

I have the same problem and i really am wondering how to fix it, because the water just sits there and makes my interior all stagnant smelling until it eventually evaporates

did you check the sunroof drain plug? its right next to the ecu box in that back corner underneath the hood

ok i went and looked under the drivers side of the hood around the ecu... and all i'm seeing is the grommet and hole that the hood release cable goes through

No i didnt. The leak isn't in the front of the car. Its in the back. And i have already checked the sunroof drains a couple times. Any other ideas?

jibberific- thats the sunroof drain plug. pour some soapy water on it and see if its leaking through

mudpuppu- when the drain plug i was talking about leaks, a pool of water forms behind the drivers seat. i had this problem previously. if thats not it, then i dont know

Hmm well when i saw that rubber grommet/plug thing i noticed it was unseated, like it was completely popped out of the hole... Maybe that's what was letting the water in? That would make sense, i'm gonna go outside right now and fix that
