I don't know for sure on your car, but I will tell you what I know. The switch on your thermostat is probably the coolant temperature sensor. It is what the computer uses to tell how hot your engine is. The computer then will send power to the cooling fans through the cooling fan relay. Most likely the sensor is bad or the relay is bad. Most of the time it is the relay. It is possible that it is your computer but not likely.
