96 T-Bird cooling fan not working
 

My cooling fan on my 96 T-Bird with a 4.6 is not working. I have replaced the thermostat and the temp sensor with no luck. I find that when I disconnect the cable connected to the temp sensor, the fan will work so it is not the fan itself. My temp gauge is running above normal and I have had a slight loss in coolant but no visible leaks. Any ideas?
