Odometer does not read

The instrument cluster is digital. It has to come out of the dash to be serviced, meaning disassembly of part of the dash. There is a high probability one or more of the connecting pins (about 10) on the back side of the circuit board controlling the odometer needs to be re-soldered. But that is not guaranteed. I suspect you may be able to locate a video on the net to at least give you an idea of what you are looking for once you remove the back cover of the cover. I know for a fact dealerships do not repair the circuit board, they replace the entire cluster. Doing solder work on a printed circuit board is precise delicate work. An alternative is sending the cluster out to a repair facility specializing in repairing them. Or, of course, obtain another cluster and installing it yourself.
