If the cluster lights are not working when you turn the headlights on, we first need to make sure the dimmer switch is not turned off. This is by far the most common cause of this when the cluster lights are the only thing not working.
If this is not the issue, then turn the lights on and check the other components that should have illumination when the lights are on. This includes the control panel lights, clock, AC control head.
If these are all working, then the fuse that power the cluster illumination is fine as these are all powered by the same fuse.

If the cluster is the only thing not working and these things check out, then we are going to have to check the voltage on the illumination circuit going into the cluster. If there is voltage, then the cluster is the issue.
