Why is the windshield wiper on my Audi A7 not working?

I recently noticed that the windshield wiper on my Audi A7 is not working properly. It seems to be skipping and leaving streaks on the windshield. What could be causing this issue and how can I fix it?

It's possible that your windshield wiper blades are worn out and need to be replaced. You can check them for any visible signs of damage, such as cracking or peeling.

Another potential cause could be a clogged wiper arm. You can use a small brush to clean out any debris that may be stuck in the arm.

It's also important to regularly clean your windshield and wiper blades to prevent any buildup that can affect their performance. Use a clean cloth and windshield wiper fluid to clean them.
