The constant hot is the fan power off the fuse link. The switched 12v is ignition power (as per diagrams). That is good. You should be able to jump the ground, trip the relay and start the fans manually.
If you run an ohm meter across the circuits from the ecm, they should be open (infinity reading). When the car gets hot and they trip, the ground circuit is completed, giving you very close to a 0 reading. If the never happens, your ecm might be caput. I'd get a scan tool on it and see what it thinks the temperature is. If it is right & no ground, bad ecm circuit.
But why was the fan switch put in, was it overheating? How exactly is that wired?
