The contacts for the cluster often get corroded and don't make a complete circuit. Not a fun job to pull the cluster, speedo cable is a beech. More so to put back than remove. But try removing the cluster and using vinegar or lemon juice on a Qtip to dissolve the corrosion.
Removing cluster (copied from another thread)



1)



Click on picture for bigger view


Remove the 8 screws holding on the plastic dash cover

2)



Click on picture for bigger view

Remove the 2 10mm nuts

3) Reach your hand behind the dash and squeeze the tab on the speedometer cable to release it.
