Hello,
I have a 2013 Edge where the driver door occasionally won't lock or unlock. When locked by the interior button, the door lock stub pops down but then immediately pops up. So when I think that I have locked the door, I come back to an unlocked door. We have to climb in the passenger door and open it with the door handle (which works normally).
I can manually unlock the door and physically pull the lock to the up position, but the car still won't open from the outside.
Another clue would be that I occasionally I get the "door ajar" indicator and I hit OK, turn off the engine, turn it back on and open/shut the door - and it goes away.
Before I take the panel off, I would like to know if someone had seen this before and hopefully have a simple remedy.
