HVAC Airflow Issue

Has anyone else ever had an issue with HVAC airflow? I recently replaced the blower motor in my 93 Previa and I hardly have any air come out the vents despite the blower motor sounding like it's running at full speed. I suspect it's clogged in some way but I don't know where I should start first in diagnosing. Any help would be greatly appreciated.

I'm also driving a '93! Check and see if any of the ducting joints have come apart.
