Removing Fiesta Mk6.5 Scuttle

[volts]

Just as winters coming the drivers side (of the heated windscreen) has packed up drat.

Been as the fault is well documented (wires been fouled by wiper arm causing breaks etc). These wires been underneath the scuttle how would one go about removing this.

Thanks in Advance :)

I had this last winter and couldnt find any way to fix it so i toke the extreme way out, and chipped my windscreen myself with a stone rang auto glass and they fitted a new one and worked straight away, but i wouldnt recommend it tbh, i just couldnt wait and needed it doing quick ( do a lot of wittier driving ) but if you give your local ford or local garage a ring im sure they will have an idea
