When mine went it took 3 goes to get it right, the ribbon cable was placed the wrong side of the wiper arm assembly under the scuttle panel and as soon as I turned on the wiper it ripped the wire off. You might also have a solar screen, this makes a massive difference in hot weather and stops the steering wheel getting hot. (The first screen fitted did not have the solar protection). I got a genuine one fitted eventually, I believe there is a Ford logo in the bottom passenger side of the screen to denote a genuine screen. I would suggest you look at your fitted but cracked screen to be sure you get a like for like one.
