Question: Heater won't blow on 1 thru 4, but will blast on 5

Why won't my heater and A/C blow on settings 1 thru 4, but works fine on setting 5. It did not work at all and we changed a fuse...at that point only setting 5 worked on the front blower. The back blowers work just fine on all settings. Any suggestions?

    This is normally caused by a defective blower motor resistor. Power is routed through the resistor to alter the fan speed for settings # 1-4, then on #5 power is supplied directly to the fan motor.
