Hey guys, ive got an 86 k10 and my instrument cluster is acting strange, when i turn my left blinker on, all my gauges go left and when my right blinkers on they go right, also when i turn on my headlights both the turn signal light indicators turn on (on the instrument cluster only) ive also noticed when the headlights are on the gauges seem to missread at higher points (fuel level goes up, oil pressure up, temperature up) just wondering if this has happened to anyone and if so what they did to fix it, thanks
