Intermittent Radio/ Door Open Sensor Issues

[Jeremy Adkins]

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.
