2020 Tahoe rear driver side door button

[nomech]

Recently I noticed that the button does not lock or unlock the doors of the vehicle (driver side rear door) but all other buttons work fine.

I watched this video and my truck does indicate that something is happening (all doors lock and some lights turn on, mirror signals flash) but the button still doesn't do anything on the rear driver door. I tried it two times.

Is there something else I can check?

It isn't terribly inconvenient, but if I can fix it on my own, I'd like to.

Thanks.

are you under the impression that the fob unlocks individual doors? that is not the case
IT CAN be set to only unlock the drivers door, OR all doors, not 3 out of 4
I would suspect the specific door lock has a issue and NOT the fob.

Sorry for the confusion. I’m referring to the push button on the handle. Each door has a button on the handle. They all work except the rear driver side door. The button doesn’t lock or unlock the vehicle but all the other buttons on the door handle work fine.

no confusion on my part, the fob does not open specific doors, other than the system can be set to open the drivers door only or ALL doors.
so..... I would suspect perhaps a inop button on that door or the actuator has gone out.
unless you have different information......in which case I have never heard of a fob being able to open any specific one of the 5 doors (rear hatch is considered a door in this regard)
so question, does the door lock/unlock from the drivers door master switch?
even if the child lock switch was engaged it would still open from the outside
