Hi all, currently i have a problem with my serie 3 33 central lock and courtesy lamps. When i open the car doors, any of them the lamp will not light up, the roof clock switches off, when i close back the door, the clock switches back on, the lamp can get on but the central lock make a buzzing sound that comes from the relay under the steering(grey box) and the fuse is burnt. when it began to do it, it did didnt do it always, soemtimes i just shaked the wires a bit and everythign was back to normal. now it seems to be permanent, i changed the grey relay box of the central lock but all in vain. i noticed but that the fuse doesnt get burnt and i checked it and it seems that there is no current passing to the fuse(you cant see smal sparks when u try to put on the fuse). is there any other device before the fuse box, or, has it happened to someone? what should i do?
