The owner of this 2009 Ford Ka did not realise that the motor was equipped with a heated screen, until giving a lift to a friend one wet evening. When the screen started to mist up, the friend asked why not switch on the heated screen to clear the misting? When the owner switched on the heated screen, he discovered that only the passenger side was operating.

All of a sudden, this new and never tried feature was not operating and the urgency of its repair was a top priority. The little Ka was booked in for the diagnosis of the fault.

I explained that the problem may be the circuit in the screen itself, in which case the only remedy would be for a new screen, but I would have a look. Upon inspection, the problem was found to be the connection between the wiring and the terminal on the screen, this had corroded and broken away.

It took a little gentle cleaning and careful repair work to reinstate the driver’s side of the screen, which then, much to the delight of the owner, became operational again.
