My 14 has the same issue on the rear drivers side door.
Gmc sierra rear door lock problems.
A lot of times on these trucks the locks just aren t gettin pushed all the way open shut.
Purchase a replacement at autozone to restore convenience.
The contact owns a 2008 gmc sierra 1500.
The problem switched from the back door locks not working to the front not working.

Most likely an actuator issue.
Rip off the door panels and check it out.
It often does not work on cold mornings but will work fine in the warmer afternoons.
There were a few small problems.
The problem is intermittent and tempersture related.
My rear door locks will not unlock front ones work fine with remote and inside control panel.

The rear locks won t budge have to unlock manually.
The vehicle was taken to a dealer where it was diagnosed that the actuator needed.
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.
Also clip that connects lock rod to actuator.
Sometimes that rod gets to where it won t move.
I think that the relay was 12 through my local chevy dealer.
If your gmc sierra 1500 door lock actuator sticks or stops working leaning across the seat to let someone else in is a pain.
Still need to get mine fixed one of these days.
Juggling keys instead of clicking a button is frustrating and in inclement weather it becomes even more of a problem.
Cable for connection to interior door handle was much shorter than stock.
