2003 Ford Crown Victoria electrical

Hello I have a ford crown Victoria 2003 lx, recently my power window switch went out and my window was down and raining. Now I replaced it and two days later my etac wont work it illuminates but no buttons work. My blower doesnt even react or nothing reacts really. And before it finally quit out I started my car and noticed my center screen on the etac was VERY DIM so when I went to go click my dome light on to see it better it got Really bright like it should be, none of my interior lights light up, and my dome light didnt work neither, I just unhooked the battery and now my fab stopped working and cannot use it to lock or unlock my car, pls help
