The coolant temp sensor is located next to the thermostat housing. The radiator fan relay is located under the aircleaner box, bolted to the "frame rail".

Where is the engine cooling fans sensor located on a 2000 Corvette ? Screwed in the driver side cyinder head just behind the Alternator. this is referred to as the temperature sensor. Hope this helps. Mike
If radiator cooling fan it turns on only when temperature sensor reaches temp needed to cool car, then when enough cooling takes place, it gets told by sensor to turn off.
You may have a bad or weak cooling fan sensor.
The sensor that turns it on is on the water outlet. This sensor sends information to the Power Control Module (PCM) and it in turn sends a signal to the Constant Control Relay Module (CCRM) under the intake housing which turns on the cooling fan on high or low depending on if the A/C is on.
The light turns itself off if all tires are at the proper pressure (36 psi) and there are no sensor faults. If the light stays on, you will need to have the system checked for codes by someone with a scan tool.
All automatic transmission have a fluid pump. The pump is usually mounted on the front of the transmission, and turns with the engine.
The computer reads the temperature from the 2 wire sensor next to the thermostat. It then actuates a relay on the inner fender and turns on the fan. [edit] most 3.0 V6 only have a 1 wire sensor.
Answer: If you mean your radiator cooling fan, it most likely is a grounded or shorted circuit from the "cooling fan sensor" (internal) or a pinched wire. Depends on when it happened: was there any work done prior to this happening? IF not, then the sensor is most likely the issue. In this case, once you find it (normally the sensor is screwed into the bottom of the radiator), unplug one of the wires (or remove the connector) and see if the cooling fan continues to run, if the fan turns off, then replace the sensor.
Perhaps there is no problem at all with your car's cooling system! The fan(s) you observe are controlled electrically by a second engine thermostat which will turn the fan on only to support cooloing when there is little forward motion of the vehicle. The fan(s)are designed to turn freely in the rushing wind and will only turn on when your car slows and needs "wind" to continue the cooling.
Either the fan is no good or the heat sensor in your radiator, that turns the fan on is not working!!
You should bring it in for service to a trained mechanic. The airbag light comes on when the computer has detected a malfunction.
