OK -4 deg C is nothing to some of you on here. But I'm getting fed with having to wait 5 minutes till the car warms up and clears the ice off the INSIDE of the screen. Before winter the windows would steam up if the car was left in the sun so I'm thinking the problem is condensation. Carpets are dry but water must be getting in somewhere. I just cant find where. My guess is the boot as the tool kit was a bit rusty when I got the car. Any suggestions on places to look and if not, how do you guys in the really cold places get around this problem?
