Auto locking not working and not recognizing driver door opening.
Until 2 weeks ago it was working but now it doesn't.
When i turn off my car and pull key out, after getting out of my car, the car recognize that i opened a door and lock it self upon 1-2 min.
Also if i unlock a car and open a door the car recognize that and doesn't lock it self upon 1-2 min.
But when i close the door after that, the car locks after 1-2 min.
So basically there is an auto locking mechanism that recognize opening and closing door, but it doesn't react anymore on drivers door, if i do that on passenger door it works.
Also before when i open a driver door the dashboard lit up and light in the bottom of the door and inside a car.
So i guess there is something with recognizing driver door opening. On my older car there was a button in car shell which works as a switch when opening door. It usually gets jammed. But on my Alfa i don't see any buttons or switches nor in the door, nor in the shell.
How does the car recognize door opening. Is it something inside a door, in door lock, or inside a car shell, does it recognize electrically or mechanically, do anyone know?
