12 volt USB port fuse blown. Fuse location.

Paddy GC680 · May 30, 2022

Away in Portugal enjoying my VW 680. Had a few issues so far but nothing major. Switch on toilet hatch broke and step stopped working. Needed software reset and new switch fitted. Unfortunately I have managed to blow a fuse as front USB not working. Cigerette 12V points. Also the USB point at the rear next to the 240 volt socket. Checked fuses, but cannot find any information what fuses control these points. Read Manuel's and it's shocking no details are given. Any guidance would be appreciated on fixing this problem. Thanks

This might help.

Grand California 600 fuses, wiring diagram, and so on..

Hi, Took me Way too long to find that, instead of trying to locate the workshop manual downloadable online and get ripped off by some shady workshop manual site, VAG just offers them to everyone via erWin at erwin.volkswagen.de - no you dont need to be VW tech or dealer/workshop to use it...

Checked all fuses, but still cannot find what fuse controls the 12V ports. All 15 & 20 amp fuses look ok. Also now notice Truman heater has no 12V supply. Could it be something else apart from a fuse???
