Because the outside is cold, or damp and wet, it can cause the inside to do exactly the same.

The interior air is moist, mostly from your breathing. The windshield is below freezing, and will capture any moisture touching it on either side--and the outside air is dry and has nothing to deposit, so there you have it.

How do I find where rain is getting into peugeot 405 in back right footwell and under seating in back?

Easy to answer! (And easy to fix.) It's the moisture that comes from your body and breathing out. It attaches to the windows, because it's warmer (fogs them up, really). When its cold outside, that fog turns to ice (naturally). The solution is: you turn the heater on with up-vents toward the windsheild, sure. But you have to TURN ON THE A/C switch as well. Believe it or not, that balances the water-content in the air, and as you have to fight fire with fire, you have to fight air with the A/C.

Its because the air inside the car, is slighty warmer than the air outside. So condensation forms on the inside of the windshield and because it has direct contact with the glass it freezes.
