Technical Condensation inside the windscreen

[12hlx]

Condensation builds up inside of the front windscreen; this is a new phenomenon; and when its below zero it freezes...

I can't see any water entering from anywhere..in any cases, if it were the case, it would be on all windows...any ideas?

Is the heater set to recirculate rather than outside air?
are the drains in the scuttle clear.

It will often collect on the windscreen if its parked a certain way ;-)

Remove the spare wheel.. is it dry in there.?

Does the car get HOT on a regular basis.. does the coolant level hold ok?
