I am having issues with my rear locks. I don't know if it is just the actuator or what. I used a multi-meter and I am getting voltage to the switch. When I hook up the switch and hit the unlock button I am getting power to the blue connection. When I hit lock there is no voltage. There is no voltage on the red or black connector. I have no idea if this is normal. Is there a way to test the actuator? I have it removed.
