Did you check the proper fuses for voltage? Some fuses are hot all the time, some go hot with the key on. Even if fuses are good, if no voltage the circuit is still dead. I guess your talking about the blower motor? Can you hear it running? I don't know if you auto hvac or manual hvac? I don't know if your talking about front or rear blower motor?
Get at the blower motor, if two wire connector, that should be voltage and ground. Turn on the hvac controls, check for voltage and ground at the blower motor connector. If good voltage and ground with no blower action, suspect the blower motor.
It is possible to use jumper wires from the battery for voltage and ground to blower motor connector, just for testing to see if blower motor will run, use an inline fuse, just in case.
If you want wiring diagram, I need more info.
