I have a 2013 Sierra 2500HD, 6.0 gas. Normally when I turn off the engine and open driver's door the radio turns off. Now it stays on and I have to turn it on and off manually. There must be other things that the door switch also turns off because if the truck sits for a week or so the battery (which is fairly new) drains down. Does this sound like the door switch, or is there some sort of relay that could be sticking? Thanks in advance for any thoughts on the matter.

Do the dome lights shut off like they should?
if so then less likely the door switch.
good luck diagnosing. I'd try chebbie truck forums for a greater chance of an internet solution.

That switch also turns off the interior lights if it's in the door open mode. Are you sure that maybe you may have adjusted the turn off time. I know on mine, the radio off, interior lights off can be adjusted from 0 to about 2 minutes.

Could be a few things but I think at the top of the list a BCM.

My wife's 2019 Equinox did that and the dealer had to reflash the computer. Hasn't done it since then.

"Body Control Module" A number of settings are available usually from the dash or buttons on the radio. Every vehicle is different so you will need to check your manual to find the correct way for yours.

A BCM or Body Control Module is a computer that controls the switches and relays and that kind of stuff in your truck. Weird things can happen when these go bad. Check the door switch out and if that checks out ok then the BCM would be where I would go.

Good luck.

Like one of the others said, I can adjust mine with "setting" function on the radio display. yours may a bit different.

Thank you all for your help. I have found that pulling and then replacing the fuse to the radio will "reset" things for a day or two then the problem re-occurs. I have an appointment with the dealer next week. I'll let you know how it shakes out. I'm an old school kind of guy and when it comes to computer controlled trucks I'm way out of my league. Thanks again to all. Safe travels.
