I am having the same preoblem your guys are having, and the issue i am trying to solve is that i have water accumulated under the carpet on the rear floors. I removed the rear floor mats and there seems to be a lot of water accumulated under the carpet. I press on the floor and wate comes out of the hole in the carpet. How do you remove the water? I really dont want to drill the bottom of the car!!!! I guess I could remove the carpet but that seems like a lot of pain. I noticed underneath the car there are two plugs right under where the water is accumulated. I wonder if I can pull this plug and the water will come out. Anyone had this problem?
