could be the cicuit board in the back of the inst cluster but I would check fuses first

possible wiring issue.
its a simple fix the odometer cluster has gone bad, I know this because mines is out. on YouTube is a tutorial on how to fix it yourself without the expensive cost of going to a mechanic. I am going to fix mines soon all by myself
