How can I troubleshoot my Audi A5's sunroof not opening?

I have an Audi A5 and the sunroof doesn't seem to respond when I try to open it. It worked fine before, but now it just doesn't budge. What are some possible causes for this issue and how can I fix it?

One possible cause for your sunroof not opening could be a blown fuse. Check the fuse box and replace any blown fuses with the proper amperage. This may solve the issue.

Another potential cause could be a malfunctioning sunroof motor. This can be a more complicated issue to fix and may require a visit to a mechanic. They can diagnose the problem and replace the motor if necessary.

Make sure that the sunroof is not obstructed by any debris or objects. This could prevent it from opening properly. Also, check the tracks and clean them if necessary to ensure smooth movement of the sunroof.
