Customer Question
Ok I have a 2009...

Ok I have a 2009 Ford Edge sel with tow pack. My cooling fans stopped working so I just went a head and replaced the fan control module fired it up hit the AC and fans came on as it should. Ran it up the road everything is fine. Wife drives it the next day and says her temp gauge was high and AC not working again. So I pulled the module tested supply power at 12.6v no output to the fans. Next I jumped both fans to 12v power and they ran fine. One of my concerns was this morning with the key off and engine cold the supply to the module still showed 12.6v power to the unit? Should this only be getting power from the PCM ONCE the temperature sensor in the head shows higher temp or when AC is cycled or does it always have power?

The violet/gray wire at the cooling fan module is hot all the time. The pcm duty cycles the ground on the white/blue wire.

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Rich DUSA

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.
