The central Locking on my drivers side door does not work. If I press the remote all the other doors lock accept the drivers, the led by the door button does not light up or flash, the drivers side door mirror does not move if you set it to that side it operates the other side, and the roof light does not come on when you open the door. Now I imagine it must all be related? Is it likely to be the mechanism or micro switch or something else?
