Vehicle located in FL. Headlights are turning on after the car has been turned off for at least 30 minutes, sometimes 2 hours. Causing the battery to be drained.
Jumped the battery. Car started and functioned normally. Changed some relay switches, disconnected battery for the night, reconnected battery. Car started with no problem. Drive approx 45 minutes then parked the car this morning, lights were confirmed to be off. 2 hours later the headlights are back on. No one is near the car when they turn on. Went to the car and started the car with no problem, but high beams will not turn on and headlights will not turn off. Turned car off, restarted it, then could turn lights off and on, and the high beams were working again.

Any solutions? I did not see a recall related to this

You may need to have someone with a GM Tech2 scan tool or equivalent check for faults in either the Headlamp Driver or Body Control Modules.
They are what controls things.

Have the Body Control Module (BCM) checked out.
