Where can I find a drivers side door lock actuator for a 2010 Jeep Liberty?

The lock actuator in the drivers door of my 2010 Jeep Liberty has stopped working. I've looked a good bit online but what I've found so far is never crystal clear that it's the right part. Do you know of a good site where I can find one and be comfortable that I'm getting the right part? Have you ever had to change out a door lock actuator and have any advice?

I've already had the door panel off and looked at everything inside the door and it appears to be a really easy fix if I can just find the right part. Thanks!

Any jeep dealer will have it or can order it.
