Ever since I owned the car my power door locks haven't worked. You push the lever down on either door and it does nothing. There is no sound like something is trying to move, just the switch clicking when you push it. I thought it might be a fuse but there's no fuse for the door locks. Then I was reading about the door lock control unit. Does this seem right? Tried the child lock thing and that doesn't do anything.
