It's a Napa Garage. I would assume he has the newest tools. Not sure why they can't figure it out

I have had my son's truck at the shop for over a week and they are having a hard time finding out what is draining the battery. It's a new battery. There is a very very soft high pitch noise you can hear from the wheel wells and under the truck that will shut off when I turn the light switch all the way to the left but will come back on after some time. I can also make the noise stop and the battery won't drain over night if I pull the #39 fuse from under the hood that is labeled IGN/MISC. So far the mechanic can figure it out. I looked up the wiring and attached the screen shots. Could it be the Multifunction Led Control module?
