If the blower motor does not function, it is blown fuse, defective blower motor, defective blower motor resistor pack, or in rare instances a defective blower motor speed control switch. Check the fuse. If it is OK, apply 12 volts directly to the blower motor and if it runs, you probably have a defective Resistor Pack. Very common problem. The only fix is to replace it.

1989 Chevy Corsica has no heat or defrost or blowing at all why?

If you feel no air blowing at all (when you are not moving) then your fan is not blowing. If it is blowing air, and it is cold, when the heater is on, then most probably your heater core is leaking, or is clogged. These are easily replaceable and go bad all the time in older cars.
