My passenger side (US) front door will no longer auto lock. The actuator solenoid extends fully and then retracts, so the solenoid seems to work ok, it just doesn't latch. If I lock it manually, it will unlock. Adjusting the position doesn't appear to help. If I lock it manually, it will unlock with no problem. I've played with the adjustment but no joy.

I've been reading the forums, but I'm out of ideas.
