TB LTZ 6cyl 2001. Runs fine, battery 12,7V, alternator 14,65V. At present - brake/airbag/abs/charge indicator stay on - no gear indication - 4 gauges no indication - hi/lo gear switch does not work, no light - fuel low light works, no gauge. Erratic variations incl: - no indication/lights at all - hi/lo gear switch/light ok - EVERYTHING ok Diagnostics: no DTC. Can't be fuses, nor steppers, as sometimes ALL instruments work. I've also had headlight washers spraying and headlights ON at ignition ON. Seems intermittant fault of data/power/ grounding at common module, like dashboard/ignition/steering column
