Does anyone know which fuse is for the sunroof? I've given up on fixing it for now and have sealed it shut with some clear silicone sealant. I would like to pull the fuse in order to prevent someone from accidentally operating it. Thanks.

Most likely due to the voltage it is a relay with a large capacity fuse in your relay/maxifuse center.

Schematic shows a 20 amp RAP fuse in the rear fuse block.
