So here’s my progress. I’ve disconnected to overhead light console, backseat above window lights, trunk light/ and checked wiring on trunk hinge, and removed light bulb from glovebox. Still drawing .061 amps. When I pull the 10amp fuse it drops to.38 now and fluctuates between .22 and .042amps (probably due to cheap multimeter) at this point I’m not sure if the .061 draw is a big deal. Battery voltage is at 12.67. I’m gonna keep the fuses in and check battery in 24 hours to see if there’s a significant drop. If not great. If so, I guess I’m onto the door panels or just go without courtesy lights. I can always get a battery operated stick on light if I get desperate. If any has any other suggestions on what might be still going on would be greatly appreciated. Thanks again for everyone’s advice. It’s definitely been helpful.
