Wet floors! Help!

[surferdroz]

I have a 2005 hatchback with no sunroof and proper sealed windows and no AC. The floor on the rear driver side is pretty wet. I pulled the carpet and under that and the padding there's a small puddle and I don't want it to rust through. I don't think it's antifreeze but not 100% sure yet. Has this happened to anyone before or does anyone know what it may be?

Yes. This does happen to my 06 hatch. I have no idea where its coming from but a small puddle does develop after a rain.

does it happen when driving or it just sitting and is there a plug like under the padding? This plug is oval anyway get a can or 2 of undercoating spray where the plug is till it seals some times the rubber around the plug rots . good luck.
