Hi, I have had a persistent parasitic drain on the my van listed above, draining the battery within a day or two. I have narrowed the issue down to which circuit it's on; the draw on the battery when everything should be off/asleep while parked is around 360mA, and when I pull fuse #7 from the driver side interior fuse box, the draw drops to around 20mA. So I know that the issue is somewhere on that circuit. But I don't have the applicable wiring diagram(s) and haven't been able to find them online. If you have access to the diagrams and/or pointers in locating the source of the draw, I would be quite grateful. Thank you!

Good afternoon,

This fuse controls a lot. I attached a diagram of all the components it controls. I would disconnect one at a time until the draw drops down. 50 to 75 milli amps is normal. I would start with the body control module.

Looks like it will take some time to do this. Take your time and keep me updated.

I attached the diagram below for you.
