Hi,
Do you mean the digital speedometer isn't working? Does anything work on the center portion?
Without a scan tool, I'm not sure which direction to go. There could be a wiring issue with the cluster, the cluster itself may have failed, there could be a breakdown in communication via the can-bus, and so on.
Make sure the connection at the rear of the cluster is tight and fully seated. Also, I attached the wiring schematic below of the instrument cluster. Take a look through it and let me know if it helps.
The schematics were two pages long. I had to cut each page in half to make it readable for you. I did overlap them so you can follow from one to the next.
Let me know if this helps.
Take care,
Joe
