Bought a Crossland x 2019 1.2 engine very low mileage with electric fault, sadly didn’t know it had French wiring ( how could Vauxhall agree to that ) , noticed it’s has a new fuse box inside,radio always works, no power to dash or much else , oddly if you slam a door mostly passenger front dash lights up and radio comes on like my mokka x , can’t find any fuses blown that I, all 3 fuse boxes have 12v , electric windows are down, they show 7.5v but how French there all black wires
