The power lock on my driver door is not working. I’ve replaced the actuator and still nothing. I know it’s not the switch because it works to unlock the other 3 doors. I’ve also checked the fuses and no problems there either. I’m thinking this is an electrical issue and power is not getting to the actuator. Does anyone know more about this?

 

similar problem. rear diver side door for my Silverado. Walk rod activates upon lock/unlock simultaneously with other three doors so I'm assuming motor works fine, exterior inspection reveals unremarkable and well greased, child safety works when activated but when I go to lock it (lock rod goes down) it still remains unlocked! From both interior and exterior. I can tell from interior because for all four doors on LT trim when doors are locked one needs to pull the door handle twice to open door. All three other doors work just fine. Dealer does not offer refunds after ten days. Just purchased a new actuator ($120 with shipping) from .com%2F&stzid=UgzhLOZxAsthlrJ6w4t4AaABAg&redir_token=QUFFLUhqa1FGWXIzSnF6VGtjYkdtTzN4cjdmeS11OENKd3xBQ3Jtc0tuc1FQdHJxdEhhMlJXRHZLR0tFQ05kd3pDTzlzMEhEcHRFbmxPRlVjSHh3NEZERmdkcjd1VFdzdlFLQkxodHBSS2FZZUNpQWhsa3JGdU54UjhFN0thS0VCS01rdUtwXzRKakZEXzJyX1VMQjl4VXVlNA%3D%3D&event=comments.
