No door panel or any interior light come on. I can’t locate the correct fuse to check it. Automatic door locks don’t work.

There are multiple ground points on a vehicle's chassis. Sometimes it just happens that they become loose or break contact altogether. Trace the ground to your fusebox and hotwire it to the battery's negative and see if the lights come on.
Keep in mind that some vehicles use positive ground and some negative. If you mix them up you could fry some sensitive electronics.
