1. Bad fuse - Always check your fuses first (which you already did) 2. Bad blower resistor - This is located in the heater case next to the blower motor (normally has four wires). Check continuity to ensure that it works. 3. Bad blower switch - Check continuity on the switch to make sure it works. 4. Bad blower relay - This is a little more complex to check, but you should should essentially have two grounds and two currents when the blower setting is on. 5. Bad blower motor - If you have both power and ground directly to the blower motor and it is not on, then the motor is bad.
