If you can get your instrument cluster out (let me know if you need instructions), simply open up the case and there are (if memory serves) 4 bulbs which light up the gauges. You can get brand new bulbs from the dealer for less than $1.50 each. Simply replace them (I would recommend doing all of them at once, cuz sometimes the removal process can finish off the other old ones) and if the connectors are corroded, clean them up. Put everything back together and reinstall. Takes an hour at most, depending on how thorough you are.
