I have a 2008 ford mustang gt with the 4.6 5 speed. The other morning I went out to start it and the battery was dead. So I tricked charged it for the day and when I got home o hooked up the battery and the head lights won't go out. I replaced the headlight switch but that didn't do anything. So I just shut everything off and just sat there. The lights went out and then I herd the locks pop and lights came back on. Sp I sat there for a bit longer and it did it again. I also could not lock it...
