I'd say the cluster needs repairing
If it's the only thing of the dash lights that doesn't work if it isn't then the headlight switch needs replaced

How would the headlight switch stop the gauges from working?

The plug on the rear of the cluster is known for having the power terminals losing good contact. Here is a YouTube video showing how to tighten the power connections. You might want to add the year of your escalade to your profile.

If you have no cluster parts working (dials or display) then its likely power supply issue, have you checked the fuse?

Power supply issues wouldn't allow the dash lights to continue working normally while the displays don't

My wiring diagrams that I paid for does not show the instrument back lighting is is fed from the cluster so they will illuminate when the cluster has power supply issues. The circuit that feeds the lamps also feeds the lamps in the radio and climate control. The fuse, that SFX Group suggested, that you need to check is under the hood and is called IPC/DIC and then I'd proceed to check the connector on the back of the cluster.

Something similar happened to mine, none of the gauges worked but the blinker lights and engine light worked fine. If this is the case, more likely than not it will be a diode inside the board. The solder brakes and makes all gauges and display loose power.
