Welcome to the forum!

A new Driver Door Module needs to be programmed to match the options specific to the VIN. If you pulled a used module, say, from a junkyard truck that has similar options it should work fine. Then it's likely not that DDM.

I suggest looking at the wiring harness near the driver's door hinge; that harness gets worked a lot and wires can break.

Also a bidirectional scanner would greatly increase your chances of diagnosing the fault.

if you get the same results with the old drivers door switch and the new one then you likely have a wiring problem between the door switch and BCM, as already noted check where it gets wiggled the most at the door jam, a broken or pinched wire or bare wire touching the frame or other wires could be the issue.
you might try getting a meter and check each wire for continuity & short to ground between the door switch and bcm
