I have just been out in the freezing rain, coz mine had stopped working too. Its in the engine fuse box (right hand side of engine under a black cover) you have a bank of fuses on the top and under all the wires at the bottom (nearest to you when standing at the front of the car) there is another row of fuses, its the third one from the right, a red 10. This is on a 1.4 diesel HDi but I assume it will be the same. Good luck
