1. Park your car in a safe location and turn off the engine. Allow it to cool down if it has been running.
2. Open the hood of your car and locate the fuse box. On the 1999 Mazda Millenia, the fuse box is located on the passenger side of the engine bay, near the battery.
3. Remove the cover of the fuse box to expose the fuses.
4. Locate the fuse that controls the dashboard lights. The fuse for the dashboard lights on the 1999 Mazda Millenia is typically labeled as "INSTR CLUSTER" or "DASH ILLUM."
5. Use a fuse puller or tweezers to remove the fuse from the fuse box. Be careful not to drop the fuse.
6. Inspect the fuse for damage. If the fuse is blown, you will need to replace it with a new fuse of the same amperage.
7. If the fuse is not blown, proceed to the next step.
8. Locate the dashboard light bulbs. On the 1999 Mazda Millenia, the dashboard light bulbs are located behind the instrument cluster.
9. Use a small screwdriver or pry tool to carefully remove the instrument cluster from the dashboard.
10. Once the instrument cluster is removed, you will have access to the dashboard light bulbs.
11. Remove the old dashboard light bulbs by turning them counterclockwise. Be careful not to drop the bulbs.
12. Install the new dashboard light bulbs by turning them clockwise until they are secure.
13. Reinstall the instrument cluster into the dashboard.
14. Replace the fuse that you removed in step 4.
15. Close the hood of your car and start the engine.
16. Test the dashboard lights to make sure they are working properly.
If the dashboard lights are still not working, you may need to have the electrical system of your car checked by a qualified mechanic.
