Guess I have to remove the passenger side front door panel to test the new actuator. If it works, then must the air tube. I would be very upset if it is a defect new actuator. By the way, why the actuator needs power connections? What's that for?

Given the route that the plastic hose has to travel to get from the pump (where is it in an S-class?) and through the accordion rubber into the door, I suspect a leaking or kinked hose, possibly in or near the door-to-A pillar accordion rubber, or a binding lock as Barry wrote. Test that by pulling/pushing the inside door lock knob or by turning the key from the outside. Compare to the passenger door.
