'79 aux fan not working

Just looking for some confirmation. My aux fan does not come on when the temp gets to the red warning light. I don't have the a/c working at the moment. According to the wiring diagram should come on when either the a/c is on or high temp condition. I have directly hooked up the fan at the main connector and it works fine. I have also jumpered the temp switch at the bottom of the radiator and it works fine. This lets me know the relay and fuse are OK. So this leads me to believe the temp sensor does not work anymore and needs to be replaced. Have I missed anything?
