Has your tailgate locking actuator mechanism quit working when using your key fob? Here's how to replace and fix the actuator. It's not too hard to fix but there are a few tricks to make it easier and ensure success!
This is for all models of 2016-2019 Chevy and GMC trucks equipped with the locking mechanism that locks and unlocks the tailgate at the same time as your door locks.
Actuator Part Number: 84374353 confirm before buying to make sure they haven't changed part numbers since I made this video.
(I bought mine from the AC Delco store on Amazon for about $50US)
Tools needed:
T-15 Torx to remove tailgate panel.
10mm socket to remove the 2 bolts.
A pick is nice to help unplug the electrical socket but it's not necessary, a screwdriver could also be used.
