My dash lights went out, all other lights work. I had the BCM scanned and no code came up. The fuse’s are all good. When it get dark the head light come on however the shifter & radio lights go dimm.
There are four fuses that power the instrument cluster/dash lights. Make sure to check all four. If all fuses check good then you may have a sensor issue or wiring issue. If all sensors check OK and wiring checks, then the cluster itself is defective.
