My wife’s 500 Popular 2013 plate has a strange issue. Until recently when she opened the car using the fob, apart from the hazards flashing the side lights use to illuminate as well. I have noticed that this no longer happens. The hazards flash as normal but the side lights no longer come on. I have checked the menu but there is nothing on there. Anyone have any ideas? Thanks

So that should not happen in the first place, its almost certainly the hatch wiring issue, all the wires gradually break shorting out, lights go out, wiper does odd things etc, look there first where the flexible is see this thread
