I woke up in the morning and my headlights were On. No other lighs were On (exterior or interior). Ignition is off, key is out of the ignition, and light switch is in the off position. I pulled out my light switch and I also pulled the light senesor on the dash (turns headlights automatically when it get's dark outside), and that did not fix the problem. I have a 2003 Ford F350 with a 5.4 Liter gasoline engine. Any assistance would be much appreciated.

 

have you checked volts at the switch when it is in the off position? Have you checked the Head light control module?

 

I have not checked the Head light control module. Where is that module located?
