So, I've been scouring through here and other places for days and I haven't been able to find an answer. So, here we are. The other day I noticed a mildew smell in my 2017 Focus ST3. I eventually pulled up the front passenger side carpet and discovered the floor pan was very wet and the sound insulation was saturated. The confusing part, the carpet is not wet at all. It is only in the very center of the floor pan, nothing up the firewall or sides. I dried it well over two days with a fan, the water returned. I have checked all of my drains and they all are clear. Any ideas?
