Door Lock Problem (2012 Hyundai Sonata)

The process in this video will help you understand how door lock actuators function, keep in mind they are not all the same. A simple voltmeter will work and even a test light (depends on the application). In this video we are working on a 2012 Hyundai Sonata. The customer complaint is that the rear doors wont lock or unlock with the remote or buttons on the door. I hope you guys enjoy this video and thanks for watching.
