Start with the simple and check the fuses, relay and the blower motor wire harness it self for 12V. If there is 12V, then your blower motor has gone bad.
Note it could also be your blower motor resistor, but if you have your heater set on high. The blower resistor is by passed and will confirm if there is power to the blower motor.
