1. Check the fuse: Start by checking the fuse that controls the interior lights. Locate the fuse box, which is usually inside the cabin or under the dashboard. Refer to your vehicle's manual to find the specific fuse for the interior lights. If the fuse is blown, replace it with a new one of the same rating.

2. Inspect the bulbs: If the fuse is not the issue, it's possible that the bulbs themselves have burnt out. Carefully remove the cluster and console covers to access the bulbs. Check if any of them are burnt or loose. Replace any faulty bulbs with the appropriate replacements.

3. Clean the connections: Sometimes, dirt or corrosion on the electrical connections can cause the lights to malfunction. Use electrical contact cleaner or rubbing alcohol to clean the connections on the bulb sockets, cluster, and console. Ensure that the connections are dry before reassembling.

4. Test the switch: The headlight switch itself could be the culprit. Test it by pulling it out to the position where the interior lights should illuminate. If there is no response, the switch may need to be replaced.Consult a professional or refer to the vehicle manual for instructions on how to remove and replace the headlight switch.

5. Seek professional help: If you are unsure about performing these steps or if the issue persists, it may be best to consult a professional mechanic or an automotive electrician. They will have the expertise and tools to diagnose and repair the specific issue with your car's electrical system. Remember to exercise caution and disconnect the car's battery before working on any electrical components. Safety should always come first.

I hope these suggestions help to resolve the illumination issue with your 1993 Cadillac Eldorado. Good luck, and drive safely!
