Nissan NV400/Renault Master 2012. I have lost my electric mirrors, blower, radio, gear upshift/downshift indicators and all interior lighting. It happened when I adjusted left hand mirror. It has happened once before a couple of years ago, I couldn't find any fault/blown fuses so took it in to main dealer. They found "blown fuse" and replaced it. Any ideas if there are any hidden fuses that control all these items in one go anywhere?
