Their behaviour was so erratic that I couldn't even define the symptom.
At times only one or two settings worked, at other times they would not work at
all until a suitably large bump in the road made them spring into life.
I'd checked all the electrical connections for breaks and corrosion only to
find them in exellent condition, eventually the only compnent left to check
was the large wiper relay unit. It is easy to remove its cover, and on close
inspection I discovered that almost all the solder joints that hold the
connection pins had hairline cracks. The design of this relay is not good
as the insertion force required to install the relay is taken up almost
entirely by these solder joints. Also the amount of solder applied during
manufacture is minimal for the task.
So out came my trusty soldering iron and I resoldered and built up adequate
solder to all pins, ( being careful to keep each pin straight until the
solder hardens) After reinstallation of the relay , my wipers now behave
