I live in Ann Arbor, MI. I've noticed on a few recent cold mornings that there is frost on the INSIDE of my windshield as well as on the outside. I've had this car a couple of years, and this has never happened before with it.. or for that matter with any other car I've ever had.
<br/> Why is this happening, and what can I do to prevent it from happening again? And if it does, how best do I get the frost off the inside of the windshield? The scraper doesn't work on the slight curvature.
