Re: blower problem

The blower resistor is usually the problem. The high speed is on a separate circuit from the lower speeds which use varying numbers of resistors to drop voltage which drops the fan speed. Its usually the resistor for the speed just under high that causes all the lower speeds to stop working since all the lower speeds require that resistor in order to work.
