electrical issues need help.

Im having problems with alot of things. My stereo doesnt turn on when car is started up, hatch door lights come on when its actually closed but only when my driver side door is open; if its closed the hatch door light comes off, and the top front interior lights arent working and mid as well. I was wondering if i might be needing a new battery for this? Or maybe the fuse is worn out? Is there like a main source for the wires where i can just reset something? Idk.

I really dont say this often on this site, and i hope im not coming across as some sort of dick, but i really think you should consider taking it to a professional.

I agree with welfare, i double anyone online could give you an answer with so many defects present. take it to a professional its more than a new battery needed.

I have noticed that if your battery terminals are corroded, you get erratic electrical behavior such as what you described. Give the battery terminals and clamps a solid cleaning and see if that changes anything.
