If the resistor pack was done you would have nothing but "high" which essentially bypasses the resistors and connects the switch directly to the blower motor. Wifes blower quite working yesterday and am a little confused after doing some troubleshooting. So I replaced my resistor. If the blower motor only works on the last position then replace the blower motor resistor. If it does work the motor is fine.
