Another member a few years back reported that cleaning a certain ground wire was the fix. The ground location was one of the two that are next to each other, right behind the left front driver's wheel, on the body mount on the frame. One of those is the BCM ground (also look for one in a similar location on the passenger side that is for many of the interior electronics).
Other than that, the BCM might need a calibration (firmware) update or the DDM (switch) might be bad. If the DDM calibration hasn't been updated, that might also be an issue.
You've likely already found out that removal of the Driver Door Module requires removal of the door panel (card) unless you are into breaking clips and screw mounts.
Please report back with a fix, or not, so we have better knowledge about the cause.
