Instrument cluster lights not working

[Tucson4runner]

Hey guys,

Long story short, did the LED upgrade to my interior lights quite some time ago with no issues. Went to turn my lights on the other night and everything turned on except the gauges. The transmission indicator lights still worked on the dash but not on the shifter. The warning lights are also still functional its just the gauges. Checked all the fuses associated and none were blown. Any ideas? Could the dimmer have gone out, and if power is directed through that then thats why those lights don't work?

Thanks guys.

Regarding the dimmer. If you have a voltmeter you could test voltage at your dimmer plug. Also you could test the dimmer disconnected resistance when you turn the dial. If you're getting voltage at the plug, could jump out the dimmer too for a test. Easy enough to grab a used dimmer somewhere.
Overall sounds like your dash lights are a process of elimination, start with easy stuff 1st, which you've done some. Only has to be one tiny thing and they don't work.
If you can get a dash wiring diagram too, would help.
