Back by the spare tire is a 4-pin connector for the speedo that has a tendency to corrode & short out.
I had similar issues with my 81 and it was 100% this connector. I cut it out, put in new connectors and perfect ever since.
Could also be corroded / dirty connection inside the pod (especially grounds). I would start with the connector in the back since it's the easiest.
Quite a few threads on this topic if you do a search.
The odo not working is most likely the little plastic gear that commonly breaks inside the speedo.
Here is a past thread covering almost your exact same issue:

do you know if you have a a 928??
if you do then it most certainly has a spare tire well.
open the hatch lift the carpet then on the left side of the hatch floor you will see the well after lifting off the floor cover under the tire is also a battery box

What a 928 spare looks like, and it is a very tight fit:
