I know this is a common fault and there's a tonne of threads here and elsewhere about the cause and the fix for it, but I'm still a little bit confused about where precisely the fault develops and how the fix works to alleviate the fault.
I posted this on the guide with the fix (http://www.fordownersclub.com/forums/topic/27470-ford-focus-06-heated-screen-drivers-side-failure-real-reason/page__st__15), but I guess nobody checks that often enough for me to get a reply any-time soon, so I'll post it here:
So, am I right to believe that the fault develops NOT in the ribbon itself, but in the wire which connects to the ribbon? And that the fix is to leave the ribbon intact and simply cut out and replace (via soldering) the wire connecting to the ribbon with a longer one?
Seems strange to me that the fault develops in the wire when the chafing action appears to happen on the ribbon and not the wire (according to the video in the first post, anyway).
I haven't yet taken the wipers etc off to have a look at what the problem with mine is, but I'm assuming its the same issue the rest of you are having, as it's the same symptoms (driver's side windscreen heating failing, passenger's side fine).
Thanks in advance for anybody who can clarify!
