For starters, check fuse # 19 in the fuse box inside the car, although a number of other things should also be dead including the interior lights. The only other thing these two formerly simple, reliable circuits have in common is they are now controlled by the Body Computer.
If you choose to replace the Body Computer with one from a salvage yard, there is one important thing to watch out for. If your vehicle has the factory-installed Security system, you can stop reading, this doesn't apply. Any correct number Body Computer will work. If the computer isn't programed for anti-theft, it will upgrade itself automatically.
If your car does not have the anti-theft system, you MUST install a Body Computer from a car that did not have the anti-theft system. If you install one from a car that had anti-theft, the computer will have self-programmed itself to need the disarm signal from a module that doesn't exist on your car. That upgrade programming can not be undone, plus, it will teach it to the Engine Computer. As long as either computer has the anti-theft programming, it will always teach it to the other one when the ignition switch is turned on. The engine will not start until both computers are replaced at the same time with units that do not have anti-theft system programming.
