Sometimes you can spin the dimmer knob back & forth many times, and wear away enough of the corrosion to get the dash lights to work, at least at some point of the contact area. Or you can pull the cluster and replace the rheostat. Or repair it - involving removing the rheostat, prying off it's metal cover, cleaning up the contact areas, then reassembly. Or leave it off and rig some kind of jumper in it's place at the two rheostat contact pins on the cluster circuit-board, to bypass it, which will run the dashlights at full brightness.
