Hatch is shut and doors are shut, and it's not set to on position on the dash panel. It keeps draining my battery. If I yank the bulb, it should stop drawing from the battery though right?
odds are one of the switches on the doors is not shutting off. at the front of the front doors is a little switch that needs to be depressed for the switch to go out. close 1 door then open the other and presh the switch then visa versa to find which one it is. then either put something on the door so that contact is made or if the switch isn't adjusted right (not sure if they even have a adjustment ) then adjust it.
Yes, pulling the fuse should do it. Since you say you checked the dimmer switch, I like 86's idea to check the pin switches. If you narrow it down to one, they are 5 bucks at the parts store and a one wire affair.
Might check the hatch switch. It can pop out of position and on mine, the metal bracket has even gotten bent from slamming the hatch to close it, preventing it from turning the light off.
