the three possible problems to this question are . your temperature sending unit is defective ,you could have problems in your wiring harness, or your temperature gauge is inoperative. I am a licensed mechanic and i have found your best place to start is to make sure you have input power to the sender and sensor and output to the gauge and or light in the system .If you have no output but you have input chances are your wirings fine and the sending unit or temperature sensors bad , you'll have to refer to the proper manual and check resistance.If you have output to the gauge and you have the proper voltage reference at the gauge ,chances are the gauge could be defective. The most common problem is a defective sensor though.
It is possible that the temperature gauge has stopped working in a 1992 Tempo due to a blown fuse. It is also possible that the temperature gauge stopped working do to the temperature sensor in the engine having a short.

possible plugged radiator, sticking thermostat, rad fan not working, temperature sensor not working, low coolant level. that's just a starting point. possible plugged radiator, sticking thermostat, rad fan not working, temperature sensor not working, low coolant level. that's just a starting point.
Left and right stopped working? Check the fuse and/or the flasher relay. Only the left or the right stopped working? Check the bulbs.
