Oh, god, I hope it’s not that. I don’t live in a place where summers are overly bad, but I’d appreciate being able to heat my car without broiling.
(And come to think of it, ever since this went on, the defrosting of my windows has been… inconsistent at best — meaning that there’s still a lot of fog/moisture/vapor fogging up the inside of my windshield and some of my windows when it’s sufficiently cold outside.)
