2001 806 2.0 HDi Quicksilver. All my interior lights have stopped working automatically when car is unlocked or doors opened. Rear one can be turned on manually but not the others. At the same time, i think, my front cigarette lighter and rear aux socket are dead - all fuses in box seem ok - any ideas? Curiously just the n/s passenger side door open warning light has also stopped working at the same time - related?
