Hi guys, On our 2007 Fiesta, we are starting get this heavy condensation on the inside of the windscreen. By heavy, I mean it's thick condensation where, if you swipe a small section with your finger, you will pull up quite a few drops of water! Please see the below pics: This never used to happen in all the years we've had this car, but in the last year or so it has developed this problem. Any idea why this is happening? All the windows are shut overnight, so what else could be causing this?
