Having a host of issues from the pjb..illumination, park brake light, and locks. Exterior light behaving strangely as well. When I deadhead the driver or passenger window switch everything works, when I’m in accessory power everything works…ive gone over related fuses and switches, my master switch is a bit funky but all the issues are still there with it disconnected…anything else worth checking before I track down a pjb?

thanks
