My guess is that the door is open. If light go;s out when door is closed then start by pulling 1 fuse at a time to eliminate fused power. If that does not work then it gets harder as you have to go to components like the voltage regulator, horn relay and so forth.
I would suguest you start with the fuse box.

The courtesy light (and timer) will turn on every time you attach the meter across the battery. Door open or closed makes no difference. Have to disable that circuit or you are in for a long day.

Turn all the lights off in the garage or at night, an make Dam sure the light (if you have one) is not staying on in the middle glove box. It happened to me because the door had to be pushed down until the catch “clicks.”
