How can I diagnose and fix a stuck turn signal on my Audi 80?

I'm having trouble with my turn signal on my Audi 80. Sometimes, it gets stuck and won't turn off, even after I've finished the turn. How can I diagnose and fix this issue?

First, check the fuse for your turn signal to see if it's blown. If so, replace it. Next, try cleaning the turn signal switch with contact cleaner. If the issue persists, you may need to replace the turn signal relay.

The issue could also be caused by a faulty turn signal switch. If cleaning it doesn't work, consider replacing it. In the meantime, you can manually turn off the signal by gently pushing the lever back into place.
