There are generally 2 of them if you have a/c. One is operated by engine temp sensor the other by the a/c switch. They are little black boxes about 1" square. Look under the hood on one of the fender wells and both are mounted side by side. On some models they are on the firewall on the passenger side. To check to see if it the relay bad and not the temp sensor, turn on the a/c and insure the fan is running. Change places with the 2 relays and if the relay is bad, the fan will not run. If the fan runs, the sensor is bad. Depending on what engine you have the sensor is screwed into the engine in the general area of the top radiator hose outlet.
The easiest way to locate it is buy a new one from the auto supply store and then you will know what it looks like, because some have 3 different sensors for various functions.

That's the fan in the front, usually the relay is on the front of the motor right on the top. On mine there was one wire going to a sensor on the top of the motor to read the coolant temp.

On the radiator. Open the hood and its right at the front of the car. Don't touch it because it could start at any time.
