Pull the blower motor (on right side firewall) and make sure the fan blades have not came loose.
If the fan motor is working fine and the blade cage is fine, Check the switch and make sure none of the vac tubes have came loose. if their ok
then you have a blockage in the vents. Most likely a broken door switch or vacuum leak. Their are doors that close off parts of the dash to redirect the air flow depending on where you set it to go.
You will need to remove the dash to access the vent flow tubes
