Thanks guys. I found my offending circuit. I took another manufacturers under hood fuse box and rebuilt it for my use. I have a 30 amp fuse running the power windows and seats. When I pull it out, the drain stops.

So now that I know which one it is, I just need to figure out why its got a current. It isn't enough current to be a dead short, which I had in the dome light and it blew a 20 amp fuse when I plugged the fuse in.

I know it runs power to relays for the window motors, so I'm thinking that maybe a relay might be going bad.

Any other thoughts?
