This morning, when it was about 8 degrees out, I had to run out to the store to pick something up for my wife. The store was only 1 mile down the road, so I didn't bother to turn the heat on knowing it wouldn't be warm yet. However, on the ride home, I turned on the heat, but the fan didn't come on. I cranked it up to the highest setting, and nothing. Figures this happens during the week we just brought home a newborn baby.
