No dash gauges
2004 Silverado. Replaced two stepper motors, and worked great for a week.
Took the dash back out and replaced some bulbs that were burned out, and
now no gauges. Dash lights work, turn signal flashers work, check engine
light works, but no gauges. Checked all of the fuses, disconnected?
reconnected battery, unplugged? re plugged several times, but no gauges.
Any ideas, other than the circuit board?
