Drivers door will not unlock

This is the actuator and it is too weak to unlock the door. Unfortunately this is a pretty common failure of these.

Let me know if you have questions but if you want to verify it then remove the door panel and test for power at the actuator when pressing the button. If you have 12 volts then the actuator is the issue.

I am sorry. I read too quickly. If the actuator is not able to unlock then you have resistance in the circuit or no power. Unfortunately if it is the relay then you will need to replace the BCM. If you see where it says Non servicable, that means it is part of the module and not serviceable separately.

I should have clarified this because when I see this issue the actuator will move but doesn't actually unlock the lock. It acts like it is too weak and doesn't move its full travel. If the actuator doesn't even move then it very well could be the BCM/driver door unlock relay.

What I would do is go to the lock actuator and measure voltage on that circuit when pressing the button. Tell me what that is and we can go from there. If it is no voltage then yes, that relay/BCM is most likely the issue. If you have some voltage then you have a wiring issue most likely. That causes resistance in the circuit which "steals" power from the actuator and it is not able to move.
