Did you use a voltage tester at the blower motor fuse? Even if the fuse is good, if no voltage, the circuit is dead. Get at the blower motor electrical connector, Check for voltage and ground. Red wire is voltage black is ground. If you have good voltage and ground with no blower action, suspect the blower motor. Test with key on, hvac on.
