2000 Ford Ranger Heat/Air

I have a 2000 Ford Ranger XL 2.5L with 72931 miles. I was driving yesterday with the air on full, max air, when the blower just quit. Being Georgia in July, I usually run the air and have had no previous problems with the vehicle. On a hunch, I checked to see if the heat would work, but it would not. When each system is turned on, I hear the system activate, sort of like a click, which it always had, but no air is being pushed though the vents. I got the truck home and checked the fuses in the panel that control the blower and the A/C, but they are whole. Any ideas or suggestions would be greatly appreciated.
