This morning the fan for the heater did not turn on - nothing blowing out of vents to warm up the car while driving to work. Overnight temps in MPLS (near 10-15F) last night - car is kept outdoors A few hours later this morning, I started the car and fan turned on as if nothing had happened. I am able to get all levels of fan speeds not just med/high. Is this electrical in nature ? Could the cold temps have any impact on the electrical ? thanks !

maybe. if it happens again, try tapping blower motor or wiggle plugs.
