How do I troubleshoot dashboard lights not working on my Audi 80?

My dashboard lights on my Audi 80 have stopped functioning. I've checked the fuse and it seems to be fine. What could be causing this issue and how can I fix it?

First, check the connections on the dashboard lights and make sure they are secure. If they seem to be fine, then the issue may be with the dimmer switch. Over time, the dimmer switch can wear out and this could be the cause of your problem. You may need to replace the dimmer switch to get your dashboard lights working again.

It could also be an issue with the bulbs themselves. If the bulbs have burnt out, then your dashboard lights will not work. Check the bulbs and replace them if they are indeed burnt out. Make sure to use the correct type of bulb for your Audi 80.
