Default 76 blower fan question

Hey guys i'm trying to troubleshoot my 76 blower fan, it runs on the 3 speeds and turns off, but I don't get any air flow at the vents. This is the way its been since I bought the car. I've read of people upgrading to the c4 blower motor, were these c3 blowers just that crappy on air flow or do I have something maybe plugged up?

Thanks!

The air flow is poor and the C4 blower will help. It's likely there is debris built up on the evaporator blocking the air flow. While you have the blower motor out, look in there with a mirror or camera and see what's blocking it. The C4 blower will need a 3/4" spacer because the blower wheel is longer.
