electrical issues

[HiImBrian]

Well I sold my car a couple weeks ago and the kid that bought it seemed pretty nice. He didn't seem too keen on how everything works, but he definitely sounded like he had good intentions to take care of the car.

Anyways, I've gotten a few calls from him just asking easy little questions. How to turn off the alarm and whatnot. But I just got a call from him and he explained how he would take the keys out of the car and the heater as well as the brake light, oil light, and my aftermarket boost controller would stay on. It sounds like the car is stuck in "accessory" or something because these lights would all be on if that were the case. I made sure to have him clarify that the keys were in fact out of the ignition and he said this just happened.

Has anybody got a clue on this one??? This has never happened to me in the 4 years I've owned the car.
