Answers :

There is a resistor for the heating and cooling fan speed. this controls the amount of voltage to your fan, which controls the speed. usually when the fan only works on high it will bypass the resistor and use the full 12 volts for the high setting. your power locks might be part of this circuit. i would check the resistor first then check the locks. usually the resistor is behind the high low switch
