Automatically turning on when doors open, but not when pushed manually, are the interior lights. The BCM power saver came to mind, but I'm not sure. They wouldn't turn on at all, in my opinion, if it were a fuse.

The bcm controls the ground side and the lights, whether they're incandescent or LED, have a constant 12v power source.
To turn it on manually, you must first ensure that the switch is functional and secondly, that the ground wire is securely connected to the chassis (using a multimeter to measure continuity).

On top of that, I've discovered that the gauge cluster's seat belt warning ding/light is also malfunctioning.

Doubtfully a foundational problem.

They might even use the same earth terminal. (I am missing the schematic for the cable)
