Any advice please on where to look to solve an intermittent problem where audio unit and 12V sockets stop working? I suspect an earth fault, as fuses are intact. Should I be looking at the A-pillar earth point? (The cargo section 12V socket is unaffected). If it is likely to be the A-pillar earth point, is this accessed from the trim at the windscreen, or from the floor?
