Hi my wife has a fiat 500x 2015 opening edition and the passenger window buttons has stopped working on the drivers door window control. The window works fine with the button on the passenger site and I have had a look and I can't see anything obvious. All the other buttons work on the drivers side does any one have any ideas? Is there any where I can get hold of a wiring diagram so I can check the wires the plug and all the pins are fine thanks in advance.
