How can I troubleshoot a non-functioning turn signal on an Audi 80?

My turn signal on my Audi 80 is not working, and I am unsure how to fix it. I have checked the fuse and it seems to be fine. What other steps should I take to troubleshoot this issue?

First, check the bulbs in the turn signal to make sure they are not burned out. If they are, replace them with new ones. If the bulbs are still intact, you can try cleaning the contacts where the bulbs connect to the socket to ensure a good connection.

Sometimes, the issue can be with the turn signal relay. This is a small device that controls the blinking of the turn signal. Try replacing the relay to see if it resolves the issue.

It is also possible that there is an issue with the wiring or electrical connection in the turn signal system. You may need to consult a professional mechanic to diagnose and fix the problem.
