Mazda mechanic: drew. remove the connector form the pcm and the fan module. ohm test the blue wire. if resistance is more than 5 ohms, you have a open in the wiring harness. try installing a jumper wire between the blue wire at the pcm and connect to the blue wire at the fan module to bypass any fault in the harness.
