1. Speedometer cluster light is controlled by rheostat... like a dimmer...
it is one of the two knobs on the cluster... turn to far right for the max
brightness... sometime in this rheostat... the wire break (dimmer control
part)... so you have to change it out.
2.Climate control light is has its own bulb... the rest of the center
console controls are lit by one bulb via fiber optic... you know... sunroof,
windows, gearshift, etc.
3. Radio has its own light bulb... not replaceble though... I am thinking
there must be another fuse that light up your speedo cluster, climate
control and radio... go wiggle all the fuse lose in the fuse box... roll
them around to knock off the corrosions.
