hi, today on the way to work, i noticed the gas indicator light wasnt on, but the rest of the cluster was lit up. for example the temperature gauge was lit up and the rpm was also lit up, but not the gas indicator. it seems as if the right side of the cluster went out. my question is are there light bulbs i can replace it with or any fuses i can replace? i looked for fuses but didnt see anything, or do i just need a new cluster? plz help, much appreciated, jimmy.
