The last diagram I posted says 30 amp fuse. My data base seems to contradict itself. I don't know if it is fuse or circuit breaker. The terminals of the fuse or circuit breaker that you suspect, the terminal that isn't hot, check the continuity between that terminal and the proper terminal at the blower connector, If there is good continuity, then you found the proper circuit protector. It's just an ohms test, if you using a meter. Can't be voltage on either circuit, during testing.
As far as circuit protector ie fuse. One leg is voltage to the fuse. The other leg supplies voltage to the circuit the fuse protects. So with the fuse unplugged, one terminal is hot, the other isn't.
Another thing you can do. Take the connector loose from the blower motor, use jumper wires from battery for voltage and ground, use inline fuse, touch to blower connector, see if the blower works. If it doesn't, faulty blower motor.
