That reminds me of the problem I had with the driver's side wiper on my
mk 1 Escort: it lifted off the screen at anything above about 40 mph.
First of all I fitted a set of metallised plastic fins to the arms which
worked all right. Then I took the fins off and just swapped the wiper
arms over: The spring on the driver's side was weak, but the geometry
meant that the passenger side needed less force, so they both worked all
right then.
