I'll try to give it 30 seconds. I wonder if this is part of the power cut system that gives you power for a shot period to drivers window after turning car off? I may have assumed this was directly tired to the vehicle lights off customization setting.
I think it is the drivers window only on reserved power after power off. I left lights on for 2 minutes and they didn't go out in ON setting so I assume mine doesn't work like some of the others here.
