Where are the body drain holes in this car, as well as a place to find a diagram/ picture to show me

I have a small amount of water coming into the passenger side floormat of this car. I have had my heater core go out on my Cadi so I know it is not that, as it is a very sneakyl eak. There is never any standing water in the car, but you can tell it gets wet because f the discoloredness of the floor, as well as when i leave papers on the floor them become damp, them wet over the course of like a week. In additio to this, I frequently have the issue of a bunch of water condesing on the inside of my sephia's windows, so I know i have a water porlbem in the car. even when i put Dri-Z-Air in there, it soaks up water enough to use the whole container up, but will still fog the inside of the windows... Help please!
