Why is digital dashboard not working in 1994 cadillac deville?

Likely due to fuse failure, however it could mean the dashboard itself has failed. There are voltage regulators and onboard computer chips in the dash unit, that drive the displays. Also FL (flourescent) displays use a high voltage source that can fail. Another possible reason is that the dash light dimmer module has failed, but that would only cause the displays to fail when you turned on the headlights, and should return the displays to normal when lights are turned off, or during daytime running. The fuses in question would be low amperage, such as 7.5 amp or smaller. Beyond that your options would be either to find a replacement dashboard from a salvage yard, or taking it to a dealer or mechanic. I would not advise to attempt to repair it unless you knew what you were doing.

Assuming that the a/c was in good shape before it suddenly stopped working, the problem is probably the blower motor. As it turns out, this is very common.
