Delayed accessory power gremlins

[GMJim]

Recently my 2006 Silverado 6.0 Vortec Max pickup started acting up. My first indication was when I shut it off and removed the key the radio continued to play which is normal but when I opened the door the radio continued to play. I opened and shut the door three times before the radio shut off. The dome lights operated normally but when I was trying to figure all this out I noticed that there was no chime when I left the key in the ignition and the feature that unlocks the door if you are trying to lock the vehicle with the engine off and key left in the ignition didn't work either. This problem seemed to correct itself after a few minutes but did the same thing the next day. Anybody have any ideas before I start looking through my one foot thick service manuals?

Thanks

Jim

Flaky connection with the bcm perhaps?

Thanks for the reply. I think I've narrowed down to the door latch switch?

Very plausible.

This seems to happen from time to time on the GMT900. Yesterday, my truck decided to sound the lights are on chime even after i opened the door and shut them off. I had to restart the truck to stop the chime. software issue is my guess.

Update

Found the problem. Door latch switch was faulty. Only problem is the electronic part of the switch that was faulty is not replaceable on it's own. Gotta buy the whole thing. $220.00 bucks later it's fixed.

Thanks for the help.
