Okay, my battery went completely dead without me leaving anything on.... I took the battery to autozone and after charging for 45 minutes the guy said it still had no charge. So I bought a new battery and after I installed it, the car still wont turn..it just makes a clicking sound...the overhead light was flashing on and off and the headlights went from working, to not working and back to working. When I try to start it, it makes a single click sound and does nothing more. What could possible be wrong?
