RADIATOR FAN DOES NOT TURN ON

Radiator Fan does not turn on. Fan works, relay works perfect. I replaced both the coolant temperature sensor AND the temperature switch. Both are brand new. The fan still will not turn on. The only way to get the fan to turn on is to unplug the temperature switch. As soon as its unplugged, the fan runs. Once you plug it back in, it turns off and begins to overheat. I am literally at a dead end and have no idea why the heck it turns on when unplugged and not when plugged in. Remember I just replaced these sensors with new ones as well. All other fuses are good (under the dash and in the engine compartment). Any help would be appreciated.

I would start with changing the thermostat/ the coolant sensor may not be seeing the correct temp
