Check to see if the motor will only work in the purge position, if you haven't yet. If the motor will work in the purge position only, your resistor next to the fan is bad along with the motor. If it doesn't work check terminals L, M, and H on the switch. B is power in brown an white wire. C goes to the compressor.
