Question Slow current drain on 7.5a circuit

I have a drain on the 7.5amp fuse in the "Circuit 1" fuse panel. This would be fuse C2. According to the label, this powers the interior lights, under hood lights, trunk lights and puddle lamps.

I know the trunk light is going out, as I can see it turn off while I slowly close the trunk. I'm not sure about the hood lights. I need to locate the switch that controls them. I have no interior lights on. I'm not sure what "puddle lights" are, so I'm not sure where to check those.

Are there any common failures on this circuit that I should look for? Any suggestions as to what could be causing the drain?

Thanks!

The puddle lamps are on the interior lower rear corners of the doors. The under hood lights are mounted to the hood and only operate when the hood is open and the lights are on (thereby being useless at 3w ea and unnoticeable if they work). They are an option so you may not have them, but if you do, maybe the switch for those is out of adjustment or bad.

I stuck the fuse back in... I get the light in the trunk, but I don't get any cabin lights, the underhood lights don't work and the puddle lights also don't come on. This will be a tricky one to deal with.

I've pulled the fuse again until I have more time to deal with it.
