2014 Sierra power window problem

[richard wysong]

my friend has a 14 Sierra 1500 that the windows stopped working on. it has a message on the driver info that the drivers door is open even tho it's not and the owners manual says if the door is open no windows will work. my question is there a way to overide the system to get the windows up ? my theory is that it's a bad door latch on the drivers door as that icon is lit on the DIC but I told him to take it to another friend and have the BCM scanned before condemning the latch as my POS scan tool will not get into the BCM other than abs and airbag. The radio shuts off as soon as you shut the key off ala door opening. I pulled the door panel off to see how hard it is to access the latch and it doesn't look to bad except that the windows down so there may not be room to extract it once unbolted. Being the weekend I don't have access to Alldata to look at the wiring diagram to see what the 6 swires going into the latch do but I'm betting I can jump it out and get the window up but not going to willy-nilly start probing and risk damaging the control module or the BCM. Any advice is appreciated

Sounds like the sensor on the driver’s door latch is shot.  I’ve never heard about the doors being “open” causing the windows to not go up.  I’ve ran mine up/down with the doors open, did it the other weekend when I replaced one of the window regulators.

I had never heard of the door open affecting the windows either but it is clearly stated in the owners manual that it does. is the sensor replacable without replacing the whole latch? if I can't overide it to get the window up the window may have to be removed to remove the latch

So after my friend took it to a local garage they found a TSB for a bad door wiring harness, they replaced the drivers door harness and that cured the problem

That was going to be my guess. Doors are notorious areas for wiring to get broken in a lot of vehicles not just Chevys.
