How to fix Audi A4 sunroof that won't close?

My Audi A4 sunroof is stuck open and won't close. This happened after a heavy rainstorm and I can't get it to close manually. Is there a way to fix this issue without taking it to a mechanic?

Check the fuse box for any blown fuses that may be causing the issue. It's worth a shot before taking it to a mechanic.

You can try resetting the sunroof by pressing and holding the open button until the sunroof moves slightly. Then press and hold the close button until the sunroof is fully closed. Sometimes this can solve the issue.
