Issues are: Driver side door has an issue with the lights flickering quickly on the door panel. When I shut off the vehicle it still continues to flicker, even with no electric on and vehicle shut off.

    The door modules have battery power to them all of the time and power themselves down to sleep with "one eye open" so that they can respond to commands made by the Key Fobs. The first thought is either the module is failing to sleep, or something is causing it to wake fully. You are going to need to have someone with a scan tool that can monitor data bus activity and battery parasitic drain and depending on what is seen advance accordingly. The door modules have a high failure rate, but it needs to be proven. If the module needs to be replaced, it will need to be flash programmed.
