Definitely not pressing the dome over ride button. All the lights come on when I initially unlock the doors with the FOB but turn off after about 30 seconds even with the doors open. Its very strange

Not sure if model years are different but the 2004 manual says with ignition off they should be on for 10 min. Not sure if there is a DIC setting for the delay, but there might be.

@GCDenali Check power at terminal ‘D’ ‘Connector 1’ of your BCM. “Inadvertent power supply” and report back

Dome lights and the map/reading lights use the same ground but different power feed. So from what you’ve said we can gather that the ground side of the circuit is good. So it appears to me that you’re having a power issue.

Also if your radio is staying on with the key out of the ignition and you open your door then check the operation from other doors.

Turn ignition on, with radio on and all doors shut, turn off the ignition and see if the radio stays on after opening any one of the other doors besides the driver door.
