W-140--Any way to test the coolant temp sensor for the a/c system

Is there any way to test the coolant sensor that controls the fans and does it have something to do with the a/c - heat system. All of a sudden my electric fans are running all the time and occasionally the little motor that runs the coolant for the residual heat function runs without pushing the residual heat button when leaving the car. Strange electrical gremlens.
