I have a 95 sonoma highrider and just replaced the heater core so I had the dash out and when I reinstalled the instrument panel is not working properly only gauge that moves is temp and not accurate all other gauges dead. Did have to jump start it with a old charger then once started noticed the gauges where not working. Fuse 4 is good and never popped. Could I have missed a ground somewhere or maybe fried the cluster and does anyone know how to ohm test the cluster. Thanks Bros...
