No dash lights

Yep, all those other lamps in the instrument panel get their power from other circuits. Illumination gets shifter indicator, radio, maybe a ashtray lamp, all on an orange wire. Some instrument panels have 2 connectors with this orange wire in both. Thus gauge lighting on one side but not the other. Keep in mind that new bulbs are not a cure when the bulb socket and/or their contact to the circuit board is the issue.
If you are bound and determined to fix it, you will lower the steering column and pull that inst' panel. you'll do more contact cleaning on the circuit boards and their connectors.
