Mitsubishi Repair: Montero limited, temp gauge, temp sensor

Question
All the gauges on the dash display works fine. eg miles, time, date, and compass.  However the outside temp gauge now displays only dashes  ( - - - ).  I assume it is the temperature sensor, but have no idea where it is located.
Is my assumption correct and can I replace this myself once I locate it?

Answer
William: You did not put down the year or make of the car. But I think you will need to take the car to a shop and let them check it out. Could be you have a bad fuse or as you said a temp sensor. Some of those sensors are easy to fix and others are not. You should go out and buy yourself a repair manual for your car. It would then explain what you need to know and how to do it. Other wise take the car to a shop. Most parts stores have repair manuals for around $20.00 but buy a Haynes they have more pictures and are easier to understand should you go that way.
