1996 Dodge Ram truck won't start

We have replaced the starter, ignition, and put a new battery in the truck.. But before. We. Did all of that truck ran fine. But now the truck won't start the Windows won't roll down and a.C. Doesn't even come on. But if you put a starting switch on the solenoid and push the button the truck will crank but the window won't roll down still, a.C. Does not work and still won't crank with the key what could cause this
