Ford Focus heater blower not working tryed the fuses

have you checked all of the fuses as some circuits have more than one fuse.if the fuses are ok,you need to check that you have live and earth at the wiring plug going to the blower motor,if so then your blower motor is the problem,it could just be clogged up or siezed so remove and inspect.does the blower work on maximum speed?if so it could be your heater motor resistor.
