I have a 2004 hyundai tiburon gt. i drove home from work, turned off the car, ran into the house, and jumped back in to drive some trash up to the dumpster in my apartment complex. I tried starting it up and it just mad a clicking sound. the dash lights and door lights lit up and started to flicker along with the clock display (which reset to 1:00).
Also, when i left the key in the ignition and turned it, all the lights would dim, then light back up if i didnt try to start the car.
is this a dead / dying battery or something more severe?
