the dash gages and warning lights are working sometimes and then go off, and then 20 min. later come back on again. As they are comming back on, it sounds like there is something winding up, and all is well. Then some time later it goes out again. Checked fuses, tapped relays, squeezed wireing, and lit a voodoo candle. Oh help you gods of the automotive word. I'm sinking here... thanks guys Paul :headscrat

if its the trailblazer (on your vehicle profile) check the wires to the computers and every possible ground, those gauges are all electronically controlled so you cant have a cable problem (be thankful) if you find nothing take out the gauge cluster for anything missing/loose
