fordem, I was just adding to the thread titled "Doors Locking on their own"...
mind you I believe the door post switch that your talking about does interact with the lock system?...
When the doors are closed and you remotely un-lock them using the key fob but you do not actually open the doors, the doors will re-lock?
If the door is "unlocked" with the key fob and the door is then opened, and the switch is working, the re-locking of the door is cancelled.
So both switches sort of have something to do with locking the doors
(of course doors locking on their own could simply be chalked up to electrical Gremlins)
