Hello guys been a few weeks since I've been on. Just purchased a full set of Bridgestones yesterday and got myself a full set of new brakes. I came home last night and tried to put my Driver window up and nothing happened. My passenger window works fine, I tried a new motor and also tried a new Box with Buttons and neither work. I checked my motor and button box in my friends Fiesta and all works fine. I've called Ford an they are wanting 82 pounds just to have a look. I trust my fellow Fiesta Owners more on here so will put it out there before biting the bullet and taking it to Ford were my pocket will feel a big burning hole.

Could be something as simple as a relay or a broken wire in the door hinge. May be worth doing current tests on the wiring. Also check to make sure no water is getting onto the electrics.

If the components you have removed work you have lost power so I would guess broken wire or rubbish ground I think it's the same fuse for both windows but not positive a quick test with a multimeter will help diagnose it
