Ok, yea, the wire diagram lists out what works on the DOME fuse.
Auto Antenna
Cigarette Lighter and Clock
Combination Meter
Garage Door Opener
Headlight (w/ Daytime Running Light)
Interior Light
Radio and Player
And yes, w/o the fuse those items do NOT work.
I decided to research the rear hatch, there was a you tube video titled:
Rear Hatch Wiring Repair and I did a little investigation. One wire was completely severed, and a couple others with cracked sheaths. So they need repair. And hopfully that was the source of the drain. Still not sure why the cigarette lighter worked, but who knows, maybe the circuit in the rear hatch made it work without ACC/Key/Ignition on.
hoping. It'll be a pain to repair those wires (tight area)...
