I'm guessing my '06 has a BCM (assuming but don't know for sure)? I know the BCM normally controls thing like the interior lights as they fade out, or the radio shutting off after 15 minutes when the truck is turned off or until a door is opened. I've had a few issues where one of the interior lights (pass side door light) will stay on even though the interior light fade out has already occurred. It is not a big deal, as I turn on the interior lights again using the rotary dash dial, then off again and it goes out. The other day the radio stayed on even though the door opened. I closed the door and opened it again and it shut off. I'm just curious if this type of behavior is indicative of the BCM failing?
