This morning it was a frigid 25 degrees when I left for Sacramento. I washed the car last night and came out to find my car frosted over on the top. I opened my door to find that the moisture had frozen over and held the door such that it took a good pull to open them. Then I got ready to drive out and I couldn't close the door. The locks were frozen and wouldn't latch over the contact on the body. I know some of you folks live in cold climates, so what do you do when your doors don't shut? I poured hot water over the units and worked the locks up and down to where it would finally close repeatedly. What a eye opener this problem was.
