I would start with the battery in your trunk. Sounds like a short to me, one or maybe more then one. I would start at the battery... you do have an ignition fuse there atleast I know on 1g's there's a box on the positive terminal that has 3 different fuses. I believe if the ignition fuse is bad/blows, you won't be able to roll up your windows, start your car, etc. Check that, then check your terminals... make sure none are loose. Check the wires off the terminal make sure none are loose. Check you ground(s).
