blower(fan motor) do go bad, before pulling out try and get to fan connection with a VOM and check for voltage.
The heater blower may not be working properly. Without the heater blower working, the air will not come through the vents.
No, that would have no bearing on the blower motor. Check the fuse, blower motor resistro pack, and the blower motor itself.
Well in my case (91) previa the connection inside f the blower housing had vibrated loose.
inside the fule tank
It has a resistor that it located to the left of the blower case (it has a door with a piece of foam on it) behind the glove box. it has to screws on either side and a wire connector sticking out the top of it. Its pretty far back there so you'll need a really stubby screw driver.
Mounted on top and inside the fuel tank.
Inside the distributor
You could have a bad blower motor or there is a resistor inside the blower motor housing which is located under the glove box on passenger side of car (where your feet would go) That could be your problem.
Blower motor not working: could be the electric motor, or A fuse, or A short. Blower motor working: could be low engine coolant, or A stoped up heater core, or loss of vacumme to the inside of the car from the engine, or A bad water pump, or A bad thermostat.
Your inside blower motor is most likely bad and if not then check the capacitors and the wiring, but I would go with the blower.....
Pull blower its up inside hole
break the window or call a tow company
