I have a 2010 Silverado 1500. The instrument cluster is completely non-functional except for the check engine light.
The gauges do not work, nothing displays on the LCD, and no other lights illuminate. The check engine light will come on when the key is turned on, but as soon as the engine starts it too disappears.
Everything else seems to work - radio, A/C, etc. I checked the fuses that I figured could be related. disconnected and reconnected the battery. I banged on the dash in case of a loose connection, and even tried swapping out the cluster panel with another panel, and got the exact same behavior.
Would anyone be willing to share any advice or guesses? Should I change the ignition switch? Look for a bad ground (not sure where to start with that).
