The glove box door tends to warp with age and the light may be on. A penny taped to the door is helpful and cheap. Sometimes, the switch is bumped in the trunk and the light remains on. Looking through the pass thru will verify that.

The best way to find a draw, is to hook up a multimeter and watch the draw when methodically pulling each and every fuse. That will give you the circuit with the fault.

If your battery is over 5 years old, it is time to buy a new one. Mine live because I use a trickle charger on my seldom driven 854T.
