Default 1977 heater blower issues

I am new to the corvette world!! I can hear the blower running (rather loudly) but I m not getting any air moving over the heater core and out of any of the vents!! I am thinking the squirrell cage may ave separated from the motor. Before I tackle the removal, I figured I would ask opinions. Thanks for helping out the newbie!!

Well congrats on the new ride.
The noise is most likely a broken or dammaged fan, something hung in it or the like. Bearings in the motor might be toast too.
No air coming from the vents probably indicate a jacked vac switch or a leak somewhere under the dash. The car is 35 years old so your going to find more than one problem step thru the system one piece at a time.
