If that's the case, the lack of cluster lamps means that the problem is either a bad switch, bad cluster dimmer control, something wrong with the INST fuse circuit. All instrument wiring comes off that fuse FROM the dimmer and out on orange wiring
When you say “off that fuse from the dimmer” are you saying the dimmer on the headlight switch? I apologize for my lack of knowledge… I am trying to follow you guys the best I can
