Ok, so today I took out my headliner and stuff. To do this you have unbolt the dome light and the passenger lights, but not unplug them. So while I'm doing this I was a moron and left the door open (dome light on) for 3-4 hours. So I'm like, crap, my battery might die. But the car started up fine and everything. Here's what's weird...

*The clock said 1:00 and started to count upwards. But when I turned on the passenger light, the dome light, or the radio, the clock went off and "door open" light went on (on the dash). But both my doors were shut. Also, the passenger light/dome light did not actually turn on. When I turn it off, the clock comes back on and the "door open" light shuts off. But the clock is back at 1:00. Also, the radio turns on, but the sound doesn't come on except for a faint whisper if I turn it WAY up.

What could this be? A weak battery? I drove on the highway for like 15 minutes to charge it, but the same thing happened. Could some wires have gotten crossed? I don't see how, because I never unplugged anything and all I did was take out the headliner.

Somebody help, I'm really confused...
