I thought we had a "parasitic drain" article on our site, I could not find it.

Never the less, I am going give you one example of something that causes this (your cause may be different, but a "draw" is a "draw") See my answer in this link.

Go to "You Tube" and put "parasitic drain" in the search box.

You are going to find many videos on the subject, look at a few, some are going explain things better and have better camera shots and some may use different tools and meters to find the problem. Maybe one will 'have it all' to include the tooling you may already possess.

Should you narrow down the circuit (along with the fuse # and its location) I may be able to acquire a wire diagram for the circuit so you can see what is on/in that particular circuit.

Should you need a diagram, the info above for your vehicle is not in depth enough for me to find it in "Prodemand". If you can send your VIN number it would help me out a bunch.
