How do I troubleshoot the dashboard lights on my Audi 80?

I recently noticed that the dashboard lights on my Audi 80 are not working properly. Some of them are not turning on at all, while others are flickering. What steps can I take to troubleshoot and fix this issue?

First, check the fuses for the dashboard lights to make sure they are not blown. If they are fine, then the issue may be with the dimmer switch or the light bulbs.

Make sure to also check the connections and wiring for the dashboard lights. Loose or damaged connections can cause intermittent issues with the lights.

If the problem persists, it may be a faulty instrument cluster. Have a professional mechanic check and replace it if necessary.
