Could be the blower motor resistor, the blower motor, or the switch. Also check the fuse, if it is blown there is a heavy draw on the system, usually the blower motor in that case. I would usually test the blower motor with a separate 12V source to see if it works, a lot of time it has just lost its ground to complete the circuit.
