Where are you located? If it's pretty cold I'd say your fluid is frozen. If it's above 30 you may have a blown fuse or bad pump.
I'm not sure what fluid Ford uses but mine froze here in Oklahoma when we hit the teens one night.
Turn the key on but don't start the engine. Have someone at the drivers seat, open the hood and have them hit the washer button. Do you hear the pump running? If so it's a blocked/loose line or frozen.
