If this is the analog intrument cluster and the entire instrument cluster is intermittently losing illumination, remove the instrument cluster light fuse and replace it with a new fuse. It is remotely possible that the actual fuse holder wires have broken due to age and would need to be soldered back together.
If this is the digital instrument cluster and the entire display is going dead, it could be anything from the wiring harness to the BCM. If it is the digital instrument cluster, I can really only recommend taking it to a reputable shop or Cadillac dealer to service.
Nick, could not find a lot on this problem, possible loose ground to cluster. Check the attached links,

No other messages in the driver info center ?
This section provides an overview of the instrument cluster operation as well as a detailed diagnosis. The instrument cluster serves as the primary interface for the vehicle's driver.
The instrument cluster contains a microprocessor as part of the instrument panel assembly. The instrument cluster performs the following functions:
• Recognizes operational malfunctions
• Alerts the driver through indicators
• Stores DTCs which identify malfunction areas
In order to perform all of these functions, the instrument cluster microprocessor has its own inputs, outputs and program software. The instrument cluster has the capability to diagnose malfunctions in the following components:
• The sensors
• The input switches
• The components
• The systems the instrument cluster communicates with or controls
When the instrument cluster or another microprocessor-controlled module detects a malfunction, the instrument cluster may turn on an instrument cluster indicator in order to alert the driver that a malfunction has occurred. Some indicator lamps have dual controls.
Your best bet is have it checked for DTC'S diagnostic trouble codes !
if the speed range between the two are different then along with the instrument cluster you will have to change the VSS "vehicle speed sensor" in the transmission as it will read incorrectly if you do not.
When you remove the instrument cluster, the back side will have a printed circuit board that the bulbs and bulbs holders twist into.
When you receive advice from this website you have to understand that without the item in front of us, we are only able to provide "a best guess" as to what the problem might be based on you description of the defect. If you haven't described a clear and precise description of the defect you decrease the chances of an accurate reply. Thank you.
It may be possible to get instrument cluster to do a self-test? If you want to try this to rule out instrument cluster.
Press and hold odometer reset button, turn key from off to run, run is where the dash lites come on. Any stored 3-digit codes will be displayed in the odometer vf display. The vf display will perform a sequential segment test. All indicators, data controlled, will illuminate. All gauges will cycle in 12.5% or 15% increments. The cluster will automatically exit self-test. The self test does not verify serial data stream. The cluster internally commands all non-hardwired gauges and indicators to operate. The fuel level sending unit sends info to pcm then pcm sends data to instrument cluster.
I don't know if that self-test will work on your vehicle? It won't hurt to try. If all the gages cycle except fuel gage, then I suspect the instrument cluster. You can call around different shops, get an estimate for the repair.
