Sorry James - can't be answered by your description. It could be a lot of
things. No one can really suggest what may be wrong or any other such
advice when you're not even sure yourself what the failure symptoms are.
A friend of mine had an '89 Cavalier with the digital dash. It was a huge
pain in the ass. The speedometer worked fine, a few of the other gauges
worked fine, but the tach didn't work at all. You should find out exactly
what part of the dash isn't working. You can always try a junk yard dash, if
you can find one, but keep in mind they were not very common.
