Dashboard control buttons not working

My dashboard control buttons are not working and that include my airbag light on the gear liver panel, hazard indicator button, rear head rest button and the central lock/unlock button. I have checked all the fuses and they are all okay, unfortunately I am struggling to locate the electronic fuse as is mentioned in the fuse chart. This happened few days ago when I went to the filling station to fill up and check my water level, the attended pushed the hood very hard when closing it and thereafter I realized that the buttons have stopped working and my hazards cannot switch on when I press the hazard button. Do you perhaps have any idea what might be the cause? Thank you in advance.
