My car seems to be having electrical issues, overhead lights wont come on, car gives warning signs when my mirror is open on the visor, my car won't lock or unlock properly from the outside. What is this?

What is your question?

For the past 2 months my car has been doing some weird things. It started with not locking properly from the button on the door handle on the outside. Every time I would lock it, it would immediately unlock the door again. When I would go back to my car to unlock it, when I would push the button it would lock it or just not go in the proper unlock sequence. Then the overhead lights that are supposed to come on when the door opens stopped working. The lights that I can turn on inside the car are so dim when I turn them on, they may as well not be there. Every time I close the hatch to the trunk my car starts beeping at me that my drivers side door is open, same thing when I open the mirror to my visor, light doesn't work and the car starts beeping and sending me a warning that my drivers side door is open when it's not. I had the battery replaced about 6 months ago because my car was having issues starting properly and it seemed to fix that problem, now this started 2 months ago.

What makes this problem better or worse?

Not sure
