I even tested to see if there's power coming from the head plug when A/C's on. And yes there's power coming through the head plug but fan is not working. However when I did your test, by unpluging and plug back the wires,it does a lttle (jump/jolt) like it was going to turn on, but did not not. At this point, I think we're both need a new fan.
