Screen condensation?

[sproutdreamer]

Our 04 t spirit gets condensation at the botton of the windscreen when the car is left. There is no trace of damp in any carpet and no sign of water ingress anywhere. In car I have had in the past there has always been a damp carpet.

I took off the plastic grill in front of the screen and there were leaves in there but were dry. I was expecting to see a cone shaped sump with water in it but any water claearly drains away in some other fashion? I have replaced the cabin filter which was mucky but dry.

Any ideas on this?
