The instrument panel has no lights.
There is a 7.5 amp fuse under the hood for the instrument cluster lights. Check for power with the headlight switch on. There is a rheostat on the cluster itself. Turn it left or right to adjust the illumination. That is all you can check easily. If the problem is in the cluster, it is not serviceable and would have to be sent out for repair, or replaced. I recommend that you have your electric circuits tested by a trained mechanic to have this issue resolved.
