I bought a 92' jimmy s15 off my friend last week....It stopped showing everything on the digital dash except the MPH.......Now and than the rest of it light up so i know how much gas is in it etc,etc.......But than it will turn right back off except for the MPH....From what i can tell this is a wide known problem....I've seen people advertising to fix it so you don't have to buy a new digital dash, but never any replys from anyone to why, or what the problem is....Is there a way i can fix it myself, or should i just send it to someone to get it fixed........
