The door locks are a looped circuit. Meaning one switch controls both actuators. So, take off the door panels and go to the switch connector on one side. Test the power there first. If you have power at the switch, you can jump across to the other wire and you should hear the actuator work. If you don't then check the connector on the bottom of the actuator. Do this on both sides. I'll bet money you have knocked a connector loose or you have a switch that is not making contact.
If you have power at the switch and you jump around it and it works, then your switch is the problem. Check the terminals that are inside the connector and make sure that they are making contact with the switch post.
