Water is getting inside not sure from where?

What is your question?

The rear seats and floor and getting saturated and smell like mildew and mold. I haven't heard anyone else with this car say they have this problem. Anytime it rains, I wash the car, and it snowed recently and the inside of my wind shield was iced over! Any ideas of where the water is coming from? Also where are the sunroof drainage holes? That could be a solution but can't find them.
