There are a few items that can cause the problem.
1. Radiator Fan control sensor, located at lower right side of radiator. Check if it is connected. Unplug the connector and use a jumper across the terminals. Turn ignition switch ON and if the fan runs, the sensor is faulty.
2. Radiator fan control module. Turn On A/C and if fans do not come on, this item coudl be faulty.
3. Fan control unit. Testings would have to be done to determine if it is faulty.
