My legend won't start. It was fine Friday then when I went out to close it up there was a click like the battery was dead but the dash lights come on but that's it it won't crank or anything. The radio lights up but won't power on and the horn beeps but really low and I can't close the windows or sunroof. I took the battery and had it charged and tested. They say it's good does anybody have any ideas what the issue could be?
