Went to my car this morning and there was a nice layer of ice on the inside of the windshield.:huh The first time, it happened a couple of weeks ago during our first frost, but I thought maybe it was a fluke. Guess not. So now it looks like I'll have to spray the glass with de-icer and wipe it with a towel for the entire winter. All the doors and windows were shut and so was the sunroof. The vehicle is a 2006 Honda CRV which I bought last April, after our last frost of the season. Any ideas on this interior frost intrusion?
