The other day I opened my door, got into my car, started her up and all of a sudden my power windows, mirrors and radio stop working (The window still rolls down when the door opens). I got home and started looking at fuses without any luck so I unplugged my battery for 20 minuets. When I connected the battery and tried to start the car I get nothing, the dash lights don't turn on and you don't hear the fuel pump start or any other electronics turn on. The security light flashes but I have run out of ideas on what I need to check next.
