Start by checking the blower motor itself by taking it out and run power to it to see if it works. Next would be to check if there is power at the plugging for the blower motor. If not, check the fuse. All good there then it more than likely be the blower motor resistor that has gone out. Last thing would be the blower motor control switch.
