What would make my heater, vent or air conditioner blower motor not come on. on 1996 Ford Taurus

Every thing was working fine when I turned off the car. Several hours later I turned on the car and the heater, vent or air conditioner would not come on. The blower motor was not coming on and it did not make any noise?

I'd check the blower motor fuse before I spent money on anything.
