Cooling fans on 2007 ford edge not working

No the relays are not the same, the cooling fans have relays in the power distribution box. The Blower motor has a "blower motor resistor" near the blower motor.

Probably the blower motor is bad , worn brushes , armature commutator . They get worn spot on the commutator . You mite try hitting on the bottom of the blower motor housing to see if that makes it work . If it starts working the motor is bad .

Cooling fan module ! Do you know what it is ? Did your fan assembly come with new fan module . why did you replace fans in first place > 2003 Mercury Grand Marquis how to test the cooling fan

Resistors are for reducing voltage to anything in an electrical circuit, and what you describe sounds like a motor that is giving out. When hot, it cuts out or quits working, but cools down and begins again. This is most likely due to the windings having shorted out somewhere in the windings. Some motors have a breaker switch located "inside" the motor casing.

your circuit is simple--I will paste it below. suspect the blower has shorted and caused the switch to burn up. remove the blower and hotwire it to the battery to see if it works. If not, replace the blower. Then run continuity tests on the swoitch and replace switch if bad. If you have questions, please let me know. Here is procedure for taking blower out:
