The Ford Ranger temperature gauge not working can be caused by many reasons such as short, loose, or corroded connectors/wires in the electrical assembly for the sending unit, cooling fan or relay problems, and a faulty thermostat. The temperature gauge is very important because it helps maintain the proper temperature in the truck. The most likely cause is a temperature sensor that is not giving the signal to the temp gauge. The best option is to take the vehicle to an auto repair shop or the dealership so they can properly diagnose the issue. The cost for diagnosis and repair will cost about $100 - $150 depending on the cost of labor and parts. It is most likely nothing major and will only require a replacement as a worst case scenario.
