Looking for some advice on where to start sorting the problem out. Originally, radio would not turn off when exiting/door opening and windows would not function from any door. Unsuccessfully left battery unhooked overnight. Problem somehow randomly resolved and worked properly for awhile but has now reoccurred but a little different. Radio still will not turn off with door opening after key turned off (will time out) and windows will operate but only from their respective door. Driver's door will not operate any windows and the door open stays on the dash. I believe there are 2 relays associated with door opening but unsure of which ones? OR is it BCM failing? Any help/advice appreciated? Thanks.

Searched the forum but can't find anything exactly similar to this... 2015 GMC Sierra SLE 5.3 Initially , problem I am having is radio won't turn off when opening door, windows were not functional from any door but locks worked and truck drove fine. Radio eventually shut off on its own, I assume as a safety to battery. Everything came back after a few weeks and problem occurred again. This time, radio will not turn off with door, cluster indicated driver door and passenger door was open (it was not and was opened/shut to confirm) and windows work but only from the individual doors and drivers window will not function. Any help on tracking this down. Looking to replace accessory delay relay and accessory power relay unless you all suggest something such as BCM or heard there is a chronic bad ground somewhere under dash ? Thanks in advanced for any advice.
