If the tempature guage is working on the dash, would that mean it is probably working to tell fans to turn on but controller is not reacting to the signal? That same failure to turn on fan when AC is turned on would apply I assume. That is the easier fix. Its a shame you have to pay arm and a leg for a part that will work( motorcraft) over 1year( I hope)

Neither fan goes on car running & AC on

Both fans come on when signal bypassed, without car running.

2011 ford edge. My cooling fans work if I bypass the signal wire at plug into controller. Is it something in the controller or something signalling the controller. Not sure how that grounding out works. Which part grounds out the signal?

2011 ford edge the fans work with direct battery power and plug has 12.33 volts but plugged in no fans work at all. Does a sensor overide the 12.33 volts when plugged in making it react differently than direct power?
