2018 Chevy Equinox 45,000 mi. Electric panel failure.

What is your question?

After starting, the electric panel display Had no readings (-) and gauges (speedometer, rpm, oil, temp) read zero. Car drove fine. The panel was illuminated. Blinkers worked but no light indicator on the panel. Service display said service theft system and tire monitor system. Air was blowing but not cold air. Car sat in parking lot for a two hours and problems cleared.
