Hello, author here. I edited the article a bit for brevity. But, yes I started by checking all the fuses and relays. I didn't find any bad relays. Unplugging the ROOM fuse also fixed the problem, but at the expense of other interior features (like my stereo).
Hello, author here. I did do as you described first---I pulled the ROOM fuse and the draw also went away. But, at the expense of more interior features (e.g. my stereo).
