blower motor/a/c repair on 1996 Dodge Ram 2500

The air quit coming through the vents so I got a new blower motor. New motor is installed correctly and running but still no air coming through the vents. The compressor is working fine and there's no freezing of the tubes but they are cold. Could it be the switch on the climate control panel or could there be a clogged hose/tube? Thanks!

The blend door is most likely not working properly and is not allowing the air to flow through the evaporator.
