IS there power to the fuse?? If not the electrical portion of the ignition switch is bad. There is a good chance that the whole problem is because the blower motor was drawing too much current(AMPS).
Blower motor is under the hood below the w/s wiper mech. The air intake BOX must be remover to get to the blower, about a 3 hour job.
