Looks like there are 2 issues.1. is a broken steel actuator cable. It's a pain as you will have to break in from the inside to get the door open before the part can be replaced.
2. Less common but what I had. It had the same signs. i.e. not opening and hearing the right noises. But mine opened sometimes. Once a day or once a week. So no broken actuator cable. Everything was replaced and still the problem came back. It happened to be a shaved wire under the driver seat (LHD). This resulted in not enough power coming to the actuator to pull the cable in to open the door.
