Blower quits blowing AC when driving sometimes

My 2003 Dodge Ram just quits blowing AC or anything when we are driving. It usually takes some time before it quits. The blower motor is still kicking but but there is no air coming out the vents. I checked the recirculation door and it is in fine condition and works perfect. I checked the hot/cold blend door and it works. The door for the passenger side for heat works as well. The blend door for where the AC or heat goes, up or down, seems to be working as well. I can' t figure out how it works most of the time but when I am driving it just quits. You can hear the blower motor running full speed but I can't find any air coming out anywhere. I have pulled the blower motor and looked and it seems to be ok. I can't find anything blocking the passageways. Any ideas?
