Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
I got the truck jumped at work today and started right up. On my way home the lights started flickering when I was using the electric windows. It drove fine. When I shut truck off, I put charger to battery and battery is fully charged. I opened the door to try to start again and NO electrical what so ever. No lights, No engine turn over, No auto locks, Nothing, Turn the key and get nothing.. Any ideas on this one?
