No Power to Accessories
On a more technical note, try checking to see if there is power to any of the fuses to the accessories you mentioned. If none, check the ignition solenoid. If it has shorted out or failed, it won't provide power to the accessories when the ignition is on. Happened to me after a number of strange electrical occurrences. It shorted because one of the lugs was loose.
