1993 Chevy blazer, electronic dash, cant see how much gas i have or my milage?

Hi, i just bought a 1993 chevy blazer, and it has an electronic dashboard. My speedometer lights up, but i cant see how much gas i have. I changed the fuse, but i know some cars have weird things you have to do if you put in a new battery, which i did. any idea what to do?1993 Chevy blazer, electronic dash, cant see how much gas i have or my milage?Nah, those are known to be junk. Unit is most likely bad. Look for one in a junkyard, or personally, I'd buy a mechanical one and put it in and be done with it.
