I would start by disconnecting both battery cables from the battery, and touching them together for a few seconds. This resets all of the computers in the truck, so if you have one that is locked up, this will sometimes "undo" it. Secondly, I would use a booster or jumper cables to make sure the battery has sufficient power to run the truck. Though the battery has 12V on it with no load, when all of these lights and computers are turned on, the voltage will drop, and if it drops enough, it makes the computers all kinds of angry, and they won't work. Reset computers and attempt to boost vehicle, that's the place to start.
