The vehicle was taken to a dealer where it was diagnosed that the actuator needed.
Gmc sierra rear door lock problems.
My 14 has the same issue on the rear drivers side door.
I think that the relay was 12 through my local chevy dealer.
Cable for connection to interior door handle was much shorter than stock.
A lot of times on these trucks the locks just aren t gettin pushed all the way open shut.
Also clip that connects lock rod to actuator.
Purchase a replacement at autozone to restore convenience.
If your gmc sierra 1500 door lock actuator sticks or stops working leaning across the seat to let someone else in is a pain.
The rear locks won t budge have to unlock manually.
Most likely an actuator issue.

Rip off the door panels and check it out.
There were a few small problems.
That door lock piece in the door is just a plastic piece that pops in the door panel and there s a rod that goes back and forth attached to that piece to lock unlock.
My rear door locks will not unlock front ones work fine with remote and inside control panel.
It often does not work on cold mornings but will work fine in the warmer afternoons.

Sometimes that rod gets to where it won t move.
