Well, a few days ago on my drive home from work my gauge cluster and hvac illumination lights went out without warning. So I'm thinking its the TCU box since its a common thing with S13's, replaced with another and no change. My next step is bypassing the dimmer switch, but I'm not exactly sure how, I want to completely eliminate it from the cars wiring schematic just so that my illumination lights are always full bright, since I never use the dimmer anyways. Much help would be appreciated. And I checked for blown fuses and found none.
Just to clarify here are a list of things that work / don't work.
Things that work:
Headlights still work, brights work, Hazard lights, turn signals, brake lights... all of this works perfectly fine. Gauge cluster clock back light works 100% as well as the rest of the gauge cluster (except illumination).
Things that DONT work (when combo switch is on 2 or 3):
Gauge cluster illumination, hvac illumination, side markers don't light up, tail lights don't light up (but brake lights work).
