Here's the story i installed an alpine head unit and it went perfectly but after i install the head unit my central locking went abnormal.

1)When i locked the driver's door all the door's will not lock.(even if the driver's door is close or open)
2)When i lock the driver's door(THE DOOR IS OPEN)and the engine is on all the door's will lock.
3)When i lock the driver's door(THE DOOR IS CLOSE)and the engine is on all the door's will lock.
what is the problem? did i disconnect something from installing the head unit?
Help me out guys,Its hard when your central locking is not working properly.Thanks

Do you think you might have disconnected a vaccum hose? If you tugged on wires, you might have accidentally disconnected it without knowing. I would backtrack it.

Is there a vacuum hose inside the center console?Thanks
