could be a bulb or a fuse... going bad? if the digital read-outs are not working... it might be bad.

All digital readouts are working perfectly.Is there bulbs that can be changed? Or a fuse for just the lights for these 3 gauges(/speedometer, tachometer,& fuel gauge) all other lights and all gauges work fine. (except for these three that won't light up)

check fuses first. gauges are sealed so if they are back-lit then you'd have to take the dash apart.

I had to take it the dealer, they took the dash all the way out looking for a bad wire.I think they either found one or it was a control module, that they finally replaced. It Took them about 3 days at Chevy dealer and wasn't very cheap either in the end. Just A very stupid amount of $ just to have speedometer lights.I miss the old days when you could just replace a bulb(and things made sense)

There also weren't any bulbs in there at all either ,everything was just led.(thus the problemo) not that it's a bad thing (they should outlast the car actually. Lol) They Broke my vent door for my passenger side I found out later (I was quoted @ $500 to remove the dash again to repair (that which they broke) so passenger side vent will blow hot air. I kinda felt like they had blown enough hot air already in that room
