Cooling fan

I have a 1995 chevy cavalier 2.2 litre with 162000 miles. The cooling fan does not come on automatically. However when I disconnect the temp. Sensor on the motor by the thermostat the fan comes on. I can then plug the sensor back in and the fan will kick back off when the temp. Comes back down. Can you'll please tell what might be happening to cause this dilema. Thanks for any help you can give me on this matter.

Then you checked all the fuses, And they are ok, Then it narrows it down to youre fan relay switch, Its a little black box with wires coming from it to the fan wiring, near youre cars rad fan.
