If they all went out all of a sudden then I would check the fuse. If they never worked for you then take off dash pad, unplug the plug assembly that feeds the dashboard and check for 12v. Or touch one of the light leads and check for 12v. I had a similar issue when i bought my 69 mach 1. temp and fuel gage did not work as well as half my lights. Turned out part of the circuit board was chewed up and the wrong pins were feeding my temp and fuel gage. repinned it, bought new ckt board and everything worked. I also replaced all the lights for led ones.
