The temperature was 10 below zero and my heater blower quit working causing all of the windows to ice up on the inside. Fortunately, I was able to get the car home safely. I check the fuses, but could find no blown fuses. I took it into the dealer the next day (Monday) and, thankfully it was repaired under my g. M. Extended warranty at no cost to me. I had 69,560 miles on the car at that time.
