My Avalanche has a problem with the radio lights and accessories staying on after removing the key and even after opening the door. I have disconnected the radio harness and tried replacing the driver door interlock switch. I even removed the ignition switch to confirm it was timed with the key. I had to put a battery disconnect so I don't continue to run dead

any Ideas would be greatly appreciated. Body computer?

Could easily be the computer do my video finding battery drain on your car. Unplug the computer and the drain goes away that's it
