why is my odometer info light not on? on 2006 GMC Envoy

It started going out and I could bang on the dashboard and it would come back on. Now it stays out and comes on sometimes after the vehicle has been driven a long while.

POSS BAD GRD OR INST CLUSTER IS GOING BAD. CALL GM AND SEE IF THEY HAVE A CUST ASST PROGRAM ON THAT PART
Thanks for your response. What is GRD? Do you know if this is an expensive repair?
COULD BE GROUND WIRING ISSUE OR CLUSTER ISSUE. I THINK CLUSTER IS APPROX 425.00 INSTALLED
Thanks!!!
