My battery is dead on my car, but my back lights are still on. However, they are not turned on with the switch. What is going on?

Sounds like you just need a jump. if that doesnt work and the battery is fully charged then you need to disconnect the wires from the battery and clean the cable hookups and the battery terminals. You can go to a auto parts store and get a terminal wire brush cleaner. Wire brush the terminals and the hookup till all the corrosion is off and then put some vasaline on the terminals and hookups to prevent corrosion later. Hook you battery back up and see if it will start.

Hi:
Though your car seems fine without using the headlights, you have a charging problem, and need to get a couple things checked out. First make sure your battery connections are clean and tight. Your alternator belt should also be checked to make sure it is serviceable and properly tightened too. Your alternator should be checked under load, and lastly, your battery too. Most auto parts stores, such as auto zone,will check your parts for free,so you should only be spending money on what is broken!

without a wiring diagram, at first guess, a fuse or relay. which you can locate in the owners manual. or it could be the switch.

Your alternator may be on it's last leg. Start the car and while the car is running, remove the negative cable from the battery. If the car dies, the alternator is no longer working. If you have a volt meter, put the meter on the battery positive and negative. You should read 13.8 - 14.2. If it doesn't show this, and reads under that, your alternator is not charging enough to keep your accessories going.
