This may be some help to others.

Recently windows started to mist up realy bad had to have a/c on full & still didnt always work, stripped out cabin filter found to be totally blocked also plastic flap which lets air from outside jammed closed so a swift left jab now flap remains open new filter fitted no more wet steamy car!

Duly noted, wifey's Omega gets misty very easily. Not that I'm going to do anything about it, trouble I'm having with my own ATM...

It'd be worth checking the condition of the receiver/dryer if it's got aircon as well; once this is saturated the car will steam up very easily.
Mine needs replacing but considering I had the aircon re-gassed earlier this year I think I'll put up with it for a while!
