Why no air of any temperature coming from any front vents in a 2003 Ford Expedition even though I can hear blower fan working?

After a little research I found out that the registers for all the vents are opened by vacuum hoses. After checking all the vacum hoses I could find, one hose in engine bay had been severed when a new battery was installed and pinched the hose between the battery and the battery tray...one small piece of hose later, and all is working great.
