The door lock button and window button is working fine on the passenger side. The window buttons are fine on the drivers side too but the unlock/lock button on the drivers side just won’t do anything.

This sounds like a door lock switch issue. However, the way this works is the lock tells the BCM that it was pushed and the BCM then tells the actuator to lock or unlock.

So we need to make sure the BCM is getting that signal. The way to do that is check voltage coming out of the switch.

The way to do this is remove the door panel using this guide.:

Then we need to check the voltage and here is a guide that will help with this:

Below is the wiring diagram that will give the detail as well. Please let us know if you have questions and we can go from there. Thanks
