Evac fan not turning, I replaced it with a new one and still same thing. It has 4 wire and rated a 12 vdc. Getting some voltage readings of 10 to 12 volts on 2 of the wires in the harness. But not sure if it is the control board causing the problem. I do have a wiring diagram but not sure how to bench test the motor since I tried a 12 v supply and no go.
