My windows keep steaming up and getting wet overnight, any clues to what it might be? don't seem to have any leaks in the car so was wondering if it could be the pollen filter? any help would be great as i'm bored of scraping the inside of the windows when it freezes!

mine did that when my heater matrix was leaking.

Don't scrape them, i just turn heater up full sorted in 5 minutes
