Headlights and interior lights

[Nickrogers610]

So i have an interesting issue, when ever I put my car in accessory mode, my switch for the lights works fine, I can turn them all on and off. Now when the car is running, the headlights, taillights, and the inside lights that only come on with the headlights and such all come on, even with the switch in the off position. The switch works as i said it works when the engine is off, its only when the car is running.

Sounds like it has been coded for daytime running lights (DRL)
