Misty screen

[lynns hubby]

Well its that time of year again when we get misty screens early morning.
Our 2006 XC70 D5 takes forever to clear the screen in the mornings.
We use the push button for fast clear but it takes ages. I don't expect the screen to clear in seconds but it takes ages. The outside clears with a sweep of the wipers but immediately fogs up again.
I have changed the pollen filter thinking it may have been damp/dirty but it was fine. Cleaned all he leaves/rubbish etc from the outside vents still no different.
I have no leaks in the footwell and it does not use any coolant so it isn't the heater matrix leaking (thank goodness). The car is always dry inside so no condensation etc.
We have had several Volvos over the years from 240s to 940s which have been great for clearing the screen on a damp/cold morning. Is this something this model is prone to as it really is annoying especially now we are back to that time of year !!!!!
