Speedo & tach not working
I had a problem with both the speedo & tach not working intermittently.  The odometer would go blank & then come back as I drove.  The tach would not work, then the next time I started the engine it would work.  No rhyme or reason to when they would work.

When I was lubing the chassis I disconnected the three sensors on the left side of the transmission.  I sprayed the connectors with a electric connection cleaner.  Both the tach and speedo have worked since.

Hope this helps someone else.......................................

Have you checked for loose (or old/crusty) connections inside the dash? You might pull the connectors apart and spray with some electronics cleaner.
Tom mentioned some good cleaner but I can’t remember the name of it.
