Nothing. Nada. Nil. Zilch. Here's a little back ground...
Truck Stats: 2005 GMC Canyon SLE Crew Cab 4x4 with Z71 package. It has an after market alarm and remote start system (from Avital), and the previous owner had installed (and removed) an aftermarket sound system and head unit. The stock system is currently installed (with aftermarket speakers). I also have a trailer brake controller installed. Other than those items, the truck is stock, and I've owned it since 2008.
I was driving home from work yesterday, stopped by my mailbox (one of those cluster mailboxes), parked my truck, and got my mail. When I got back in my truck, I inserted the key, turned it, and that's when it all went south. No power. No electricity. Nothing happened. As if my battery had been completely disconnected. I thought that was weird, so I turned the key to off and more weird stuff happened. All of the needles started to wiggle, as if they were vibrating, and there was a low buzzing sound coming from the dash. The key was in OFF. And removed.
I disconnected the battery, went and got my tools, and started troubleshooting, but I'm lost. I have a Haynes manual, but it's circuit diagrams are pretty crappy. I'm also not sure where to go now. I pulled the battery, had it tested, and it tested fine. I left it disconnected over night, then tried again this afternoon. Now, I have no indication of power at all. Even the needles stopped vibrating when the battery was connected. I've checked the fuses (and broke one, but swapped it with one for a component that I don't care about right now).
Could this be a BCM issue? Is there anything that could fail that would cause ALL electronics to not work? Whatever it was, it had to have had a sudden failure, because I had just parked it for less than a minute before attempting to restart it when this happened. I've not been able to find anyone else who's had this issue, or maybe I don't know what I should be searching for.
Any help you guys could provide would be greatly appreciated. I'm stuck.
