Re: Body control module fuse blows
I would check all the main power leads from the bcm to the fuse and all the grounds, and do an ohm test on them as well, it sounds like you have a major short either short to + or short to - the harness itself could be rubbing through to metal, a positive wire and a ground wire making connection in the worn out area, and check all your wiring around the fuse blocks for critter damage, just some ideal's.
