Been having a few problems with my central locking system on the Z with key fobs ect ect anyways went to open it this morning with the key manually and no central locking worked at all worked at all and altough the drivers door still popped up and opened it wasn't driven buy a electric power, then I sat in the car and tryed using the locking button in the centre console, this would lock but not unlock ? But when trying to unlock you could hear something click like it wanted too but nothing happened, So I've read through a few threads about what the problem could be but my real question is what was making the buzzing type noise from the cetntre console locking switch area ? like a small unit of some type doing something ? I only thought it was a switch which wouldn't normally make any noise ?
