Yesterday my EOS wouldn't start. I figured perhaps I left the lights on, door hadn't closed all the way, etc. so we jumped the car, it started immediately and I was able to drive to the store and back. When I went out to start it this morning I noticed the car was making a clicking noise before I even got in it. It's just a constant noise that can be heard more from the inside of the car but is also audible standing outside the car. Again the car wouldn't start. We tried jumping it again and it wouldn't turn over at all this time. The clicking noise is still going as well and I can't figure out where it's coming from. Any ideas?
