Instrument Gauges not working on 2003 Mitsubishi Outlander

The gauges are not working. I can hit the dash and they will come on sometimes. I'm not sure if it's the gauge cluster or wiring...whats the best way to troubleshoot? If I replace the gauge cluster will the mileage differ from mine that I currently have?

I would look at a loose wiring problem first. Also, I believe your computer should b able to store that information if gauge needs to be replaced.
