window fogs on the inside when it is moist outside, mildew develops inside

What is your question?

Is there a seal leak somewhere that is allowing moisture inside? I also noticed a puddle of water on the left passenger back side (actually large) after a heavy rain, all windows closed, sun roof closed, I had to use a shop vac but felt water in between the frame and the carpet. (I need to remove the back seats and remove the carpet to clean it up) My gas door never has closed and I am wondering if water can leak though there? It is on the same side.
