Well, not being able to physically see or test it, that's difficult to say.
If you have multiple gauges acting up, there is a resistor (?) on back of the panel that can get out of adjustment or go bad. I would start with that.
If you don't have one get a Chiltons manual with the wiring diagrams so you can trace the wiring if you need to.
Remove the gauge panel and post a good, clear picture of the backside.
