A clamp-on DC ammeter may make your troubleshooting a bit more efficient. Some will read down to .1 - .2a relatively accurately and will allow you to check current on a number of wires/cables very quickly. I've troubleshot similar problems as yours and was able to find the source of the problem with just a couple of random wire/cable checks with a clamp-on.
Also, don't know about your Chevy, but when you open the hood or door on our Ram, it temporarily activates portions of the BCM with a several amp load. This load disappears after 5-10 min. Just something to keep in mind so you don't find yourself wasting time chasing phantom draws.
Good luck!
