My heated windscreen is dead. Owners manual shows there are 4 fuses associated with it. There’s a 60A in the engine fuse box and a pair of 30A in the passenger fuse box (RHS & LHS of screen). All these look fine.

But according to the manual there is also supposed to be a 7.5A for ‘ignition, rain sensor, heated front screen’. This one’s missing in my car. I don’t have a rain sensor but is this fuse still needed for the windscreen?

I’ve just bought car to don’t know if the heated windscreen has ever worked.

    The F1 fuse (7.5A) is required to supply 12V to the windscreen relay (R5). My car is a Fiesta 2010 Mk7. Here is the wiring diagram courtesy of Unofix 
     

    it appears my dead heated windscreen was due to a missing F1 fuse. Popped one in and now running perfectly.
