I've got a problem with the switch on the drviers side of my Polo. The drivers window doesn't work at all and the passenger one does but only opens regardless of whether the button is pushed down (for open) or pulled up (for close).

The central locking switch does nothing as well.

Using the key in the drivers door does not operate the central locking, however the central locking for both doors and the boot operates correctly using the key in the passenger door lock.

The passenger window switch works correctly.

I've checked all the fuses and they seem fine.

I've taken the switch gear out of the drivers door. Within it there are 3 switches (one for each window and one for the central door locking). They do not seem to be connected together so assume the fault does not lie within the switch itself?

Where do I go next? Is it more likely to be a wiring problem than a switch?
