So the other night I was driving my 05 convertible home and had the headlights on of course and I also had the a/c on, as I was driving I happened to notice the little clock and temp display was flickering, then it went completely out. I turned the air off and rolled the windows down and no more flickering. So here's the big question, is my battery shot? but if its bad wouldn't the headlights go dim?? Is my altenator going out? If anyone has any ideas as to why these lights would do this please let me know!!
