Hello and welcome to JustAnswer!
The blower motor is actually powered through the ignition switch rather than a relay.
Check the fuse if you haven't already.
If the fuse is good then the problem will be the ignition switch, wiring, the blower motor resistor, control head or the blower motor. The switch or resistor would be most likely, but in cases where power is fed directly through the ignition switch it's not uncommon for the switch to fail.
Resistor failures are probably the most common cause of a blower motor not working. The resistor is what steps down the available current to the blower motor to give you the different speeds. You can check for power coming to the resistor on each of the four wires for the different speeds , if there is power there then you know the ignition switch, control head, fuse and wiring are ok. If there is power into the resistor but not leaving to the blower motor then the resistor has failed.
