I have a 1994 Bonneville SSE and the DIAGNOSTIC Center on my Dash is not working. I brought the car not too long ago and the Diag Center was working then it just stopped. All the other gauges seem to be operational. Any Idea on what area to look at in order to correct this problem?

sometimes with the cluster the connections can corrode and cause the DIC and compass to stop working, I would say pull the cluster and clean the contacts.
