2013 Yukon SLT driver door module?

[2013yukonmontana]

Hello! I have a 2013 Yukon slt.
A few weeks ago I got a messGe while driving that my door was open (it wasn’t)
After that message- nothing related to the drivers control module would work and the mirror turn signal on the left stopped working. Right side still works.
Power seats still work but ac /heat seats do not. Also, power locks do not work from the key fob but back hatch still does
I replaced the fuse and it’s fine.
Should I pop the door panel off and look at any severed wires before replacing the DCM? Is it an easy fix? Trying to avoid taking it in. Any suggestions?
Thank you!

A new module will require programming. A used one from a car with same options as yours will not.

I would purchase a new one, not a used one. Are they easy to replace?

Easy for the hardware, the brains is in the switch assembly on each door. It has to be programmed to your vehicle's options to get it working, that's the stickler. Dealer can of course do it, you can buy the necessary tools and do it and have a tool that is almost paid for that can do so much more when necessary.
