The Normal Temperature Range to the Fan Start is: A/C ON 181 F. A/C OFF 199 F. When the Engine Reach this Temperature the Fan should start. Do this simple test. 1- Start the engine, Disconnect the Cooling Fan Temperature sensor (CFT) located on the Radiator, See if the Fan come ON. If yes, if not go to step #2 2- Reconnect the CFT sensor, leave the car running and with a Temperature gauge or Thermometer check the temperature, if the Temperature go more than 199 F. Turn the Engine OFF. 3- Disconnect the CFT sensor and check for Ground at the WHITE/BLACK wire, if ground exist, replace the CFT sensor. But if not, check the wire for any damaged, and the ground at the Front Left fender. Repair as need. 4- Check the Fusible link for radiator fan 30 amp. Check the Fuse link for condenser fan 30 amp. Replace if need, and return to step # 1. Check the Radiator fan Relay, Rad fan relay 2 and 3. Replace if need. . I hope this help
