1998 Toyota Avalon Car starts but nothing electrical works.

I have a 1998 Toyota Avalon and it has been sitting in my driveway for a few months. It has been driven a few times but for the most part it has been sitting. I replaced the battery today and the car starts but nothing electrical works (clock, radio, ac, powered seats, dash lights, powered locks, windows, and turn signals). The only things that work are the overhead lights, the hazard lights, and the head lights. Also, it wont go into gear. I checked all the fuses and they are all good. (under the hood and also inside the car) Any idea of what this could be? Please help.

Thanks!
