I have a 2003 expedition and my radio stays on after I turn it off. The over head lights come on and go off. But they do not come on when I close the door or open it. I changed the door ajar switch on my driver side already like months ago. I have opened all the doors to see which door it is and no light came on. I also have to manually turn on my lights they don't come on automatically anymore. I have read in some forums about the purple wire but I have no idea where it is? I need pictures, video. Yes my light blinks in the middle of the dash. Idk y my automatic lights aren't coming on. Help me please. I need to have these things fixed its driving me crazy!
