I usually have been successful in replacing a resistor without replacing the blower motor, although, a shorted (drawing too much current) motor could burn out the resistor. I suppose you could power up the motor with clip leads to the battery, and see if it runs well. If so, it's probably not shorted. If the clip lead wires melt, then the motor's probably shorted.. Don't burn your fingers..
