Testing the engine coolant temperature sensor is done using a live data scan tool. If you have access to one, simply plug it into the data link connector under the dash, go to live data, and check what signal the sensor (ECT) is sending to the computer. If the engine is at operating temperature, it should be around 200 F. The fans are designed to turn on at 210 F.
Melissa, have you checked fuses and relays? Does the fan come on with the AC?
There are two fuses and two relays in the under hood fuse box. Check them if you haven't. I attached two pics identifying them and showing locations.
Here are a couple links you may find helpful.
In addition to just checking a fuse, make sure there is power to it.
Let me know if this helps or if you have other questions.
