Barn Door Auto Lock Troubleshooting

[BamaDogg]

I am trying to fix my auto lock in the rear. When I push the button located near the rear door to unlock I hear something clicking upfront like it is trying to unlock. Nothing happens at the actuator in the rear. When I hit the button in the lock direction, nothing happens. Any suggestions? Start by replacing actuator?

I am getting power to the connection that hooks up to the switch. When I connect the switch and hit the unlock button I am getting power to the blue plug that connects to the contact plate. There is no power on either of the other two. Any suggestions?
