Hi, does anyone have a problem with the inside of their windscreen condensating up overnight? Now its dropped cold again its started doing it. Clears quickly using auto mode and the aircon. No obvious leaks, under the mats and in the boot is dry, no sunroof. Pollen filter was changed in October. I reading that maybe warm air leaks out of the screen vents hitting the cold glass causes it. Do I need to stop the aircon a few miles from home and switch the system off completely when I park? During the rains over Xmas, no problems at all. Any ideas?
