Thanks for the question.
Do you ever hear the cooling fan come on even when the a/c is turned on?
Repair history for the last year?
What have you checked or done so far?
Ok, first try with the key out of the ignition, turn the fan blades to make sure they turn freely. If they don't, look for any obstructions. Or the bearing might be froze up. If that is the case you will need to replace the fan assembly.
Check all your fuses, under the hood and inside the car. Replace any blown fuses.
With the engine running and the a/c on, try smacking the black metal module that is above the radiator under the engine decal bezel. If the fan starts to work, then replace that module.
If that is ok, remove the fan motor connectors and look for any signs of melting of the connector or overheated terminals. If this is found then the fan assembly will need to be replaced along with new wire pigtails. You can get all of this at Ford dealer parts.
Let me know what you found
With the a/c on and the engine running, can you hear the a/c compressor kick on?
Also, with it still idling with the a/c on, try wiggling slowly the connector at the fan motor. Does it come on or try to come on?
Also, do you have any test equipment like a voltmeter or test light?
Do you have access to a jumper wire or something metal to jump a connector?
Find this switch back against the firewall on the passengers side. This should be located on top of the black a/c accumulator. Remove the 2 wire connector going to this switch shown in the picture below. Now take a jumper wire and put it between the 2 terminals on the connector and turn the a/c on and let the engine idle. Let me know if the a/c compressor comes on and if the fans come on.
Don't hit accept again please.
What that tells me is that all the wiring and the fan motors are good. Now it tells me the sensor that tells the fan to come on at a certain temprature is not working correctly. That would be the cooling system switch.
But if after jumping the switch I mentioned earlier, then yes the fan could be bad and will need to be replaced. However, to verify this, you will need to test for power and ground at the fan motor to verify that you have power and ground there at the fan.
