I'm knew to WF and have been a Wrangler owner for 18 months now.
I've got a 2004 Sahara that is haunted.
The headlights turn on by themselves, even though the switch is off. I'll park it, and come back to them on, or a dead battery. It seems to happen mostly in the summer or when the engine is warmed up, thus possibly heat sensitive.
If I turn the ignition key (but not turn on the engine), it will turn off the headlights (I'll hear a clicking).
Any ideas on the cause? My first thought is a relay?
