Power door lock issues

    I have a 2002 Suburban and recently developed problems with my power door locks.

    If I try to unlock the doors with the power lock switch or the keyless remote, only the driver's door unlocks.

    If I try to lock the doors with the power lock switch or the keyless remote, all the doors lock EXCEPT the driver's door.

    Any ideas?

    Try pulling the power door lock fuse (there may be a 2nd one for unlock) to reset the feature. Maybe something is out of sync.

    Here is the issue I have with the power door lock on my 2000 1500 (without remote lock)

    I use the key to open the door and I can use the inside door lock switch to unlock the passenger side door (for my wife or kid).
    Once the truck is moving, both door locked automatically (work as expected)
    After shut off, both door unlocked automatically (again, work as expected) BUT when I use the door switch to lock the door before shutting the door, it failed. When I press the poor lock switches on both door when the truck is off, I can hear a "weak" button clicking sound seems like the actuator is not getting enough power.

    It's very inconvenience since every time I stop the truck I have to climb over to the other side to lock the other door...

    I am not sure it's the actuator or not. If it is, why the door can lock itself when the truck started to move? Or is it the switch not working? Both switches have the same issue?

    anyone has input on this?
