I have a 1996 chevy lumina and the temperature gauge keeps moving around unpredictably. The fans wont come on. We checked the fuses and relay switch. Could it be the fan motor, or temperature gauge
We replaced the cooling fan relay and the fuses

The gauge is supposed to move. Between 190 and 210 degrees. About a 1/16 to 1/4 inch movement with the needle. If it goes from middle(200 degrees) to hot(260 degrees) and back. Check the coolant level. Air pocket in the engine. Low fans come on at about 210 degrees. High fans come on at 225 degrees. High fans come on when the A/C is turned on. And it works.
