doors think there open when shut?

[cupraglasgow]

My leon cupra thinks the drivers door is open even when its shut, inside light remains on as does the saftey light on the bottom of the door.
I cant find the sensor or little switch inside the door which tells the car when the door is shut, does it have one? or how does it work?
Also central locking will not work now from remote key or manual key in the door.

Any suggestions would help.

The switch is inside the door latch assembly.
