I have the mechanical aptitude of a tadpole, but most Orgers are well-versed. Welcome to the best water-cooled Beetle site on the planet! I'll put in a word over on our Facebook page and try to steer someone over here to help.
Mine, stopped working and it ended up being a blown fuse. Check your fuses; behind the small door on the drivers side dash when you open the door. Sometimes; junk can get in there (coins, paper clips; metal objects, bad plug in devices) and this will blow the fuse, so check for debris and whether or not your power adapter is working or falling apart. Cheap charging or electrical device adapters, may cause problems or I have had them break apart, cause grounding out issues.
