Hi all, I’m hoping someone can stop me making a schoolboy error here - I’ve just discovered that my passenger (front) window doesn’t operate with the switch on the passenger door. It works fine with the driver’s door switch, and all other windows operate properly (with both driver door and associated door switches, including correct operation of the child lock). It seems an odd thing to fail on a 45k mile car! Before I start taking things apart to fault find, is there some random isolation setting/switch or something similar that I’m not aware of - I can’t see anything in the manual??
