We need to start with finding out if we have power going into the cluster on pin A16. If you do, then the cluster is the issue as the illumination circuit is getting power, but the bulb is not illuminating.

If you have an issue with the cluster then we need to remove and inspect the bulb as it may be just as simple as this.
Please see the info below and that will help with replacing this if needed.
If you have no voltage, then we need to go to the last wiring diagram attached below and trace the circuit to find out why we have no voltage.
Please run through this and let us know what questions you have. Thanks
