The description sounds like a faulty door switch or the RAP (Retained Accessory Power Module) is not getting the signal from the door switch telling it to shut down. Do other items like the windows/power seats/mirrors also stay "on" during this time?
The best way to test it would be to use a dealer level scan tool to watch what the module is actually being told to do and if the switch is triggering properly. The actual switches are part of the door latch itself so testing with the scan tool is a lot faster.
