14’ electrical issues

[HvacWagon]

New to the forum and the truck. Seems like almost every other week I have some type of electrical issue.
First started with the drivers side switch cluster. It will operate the back windows, but not the front, the locks, nor the mirrors. I do believe I have that traced to the module behind the door panel.
Secondly I started getting a notice my passenger brake light was out. Everything checked out on that end.
Lastly just last night my remote start failed to start the truck getting a “hood open” message. I bypassed the switch and I’m still getting the same code.
I don’t know much about the working of a 12v car system, but I do a lot of low volt (24v) at work with building controls.
If there’s a schematic anyone could pass along or some insight I’d appreciate it. Thinks!

Random stuff like that often resolves to the BCM.

Any way I can test for that?
