As title states miror and window hwve all of a sudden stopped working. I am thinking it is most likely thre control unit, any way of testing this or out else it could be?

Have you checked the fuse(s)?

I have same problem. Please could you dierect me to the fuses numbers.  I have a 51 plate fabia comfort.

New to me if passenger door electrics are on same fuse?

 

If it was fuse surely both sides would not work,and I would not think the mirrors and windows will be on one fuse anyway.

 

Door loom problem I would say,check the multiplug to door is in correctly
