if you arent getting airflow something must be clogged, weather its the heater core, evap, some flap for recirc(not sure how that works)

It doesnt blow at all, I even ran a hard wire to the battery straight to the blower motor and it didnt move.

Is it grounded? I would check and make the ground is not bad. If the ground is good then the motor is bad

You could run another wire. If you have a test light you could hook one end to the pos side of the battery. Then touch the other end to the ground and see if it lights.
