'01 Silverado. Nothing in instrument panel works. Oil and Temp Gauges move up upon starting but tach, speedo, odometer, gas not working. Fuses look ok, now what?
Thanks

i dunno about chevs but i know on a ford there is a sensor on top of the rear dif... i broke one off once on a ford and same thing happened but the gas guage still worked... maybe chev hooks all that up in one wire bundle... dunno... but yeah maybe that'll help...
