I keep noticing my headlights switch in the on position my headlights are not on but in the morning my battery is for real dead. How is that possible?

thx in advance

 

Is this the 2001?

Does the car have auto off lights?

Are you sure the lights are the problem?

Any after market alarm or stereo system installed?

Is the trunk light turning off when lid closed?

How old is the battery?

Have you checked the battery connections?

 

- yes
- not sure, car off key out I can still turn on headlights
- when I get In car I see headlight switch is in on position eve though I recall turning them off
- Not sure.
- received it a few months ago but it could have been switched I don’t know.
- negative seem to have been loose.

 

If equipped with auto light off, when the ign key is off and the driver’s door opens the head and taillights turn off when the light switch is on.If the negative terminal was loose the battery may not be fully charging.

Tighten battery terminals. Charge the battery up. When parking the car turn the headlight, etc off.

If you have a milli-amp meter can check for parasitic current drain when the car is parked. Place the meter between the battery terminal and negative battery connector. The internet would have info on how to do this.
