I'm just wondering if the BCM is recognizing the doors are not closed or not sure of a signal to tell it when they are open or closed. Would suggest having the modules scanned for data to see if the door actuators door control modules are giving false information even while driving. Need to find out where the glitch is.

Thanks I will let you know what the say.
