I parked my 2003 Silverado yesterday and everything was fine. When I went to start it today, I have no power any where in the vehicle, but the battery is fully charged. I checked the ground wire from the battery to the engine block and that is okay. The ground wire from the firewall to the engine block is also okay. Where do I go from here?

In the past, the past the information center has jumped from one language to another on it's own and sometimes I've gotten an icon showing that looks like a padlock around a doorpost, even though everything seems to be working okay. I'm wondering if the onboard computer has gone bad. If that happened, would it kill power to everything?

Hopefully a intermittent power issue?now total failure?gonna need a test lite,start checking large fuses in relay,fuse center
