I have been having problems with my passenger side front door lock. It goes up, but not down. anyway I took out the actuator and would like to know if any one knows the pin out. there is a four pronged connector that plugs in the bottom. also red, black and blue wires that come out the side<------what are they for? I can hook it up to a 12v power source, but what should cause the actuator to go up and down. I'm pretty sure that the prongs on the bottom are all I need to make it go up and down. dont I need like a negative 12v pulse to make it go up and down? How should I test it?
