The wipers had gotten to the point that the only setting that would work was the
"high" speed. And, then I had to turn them off at the right time to get them to
stop in the down position. Now they don't work at all. I'm hoping it's a relay
and not the motor but, I'm not familiar with the 240 to know if this a common or
know occurrence. Any help from the collective wisdom of this group would be
greatly appreciated.

Is the motor noisey? Then a magnet has fallen off the inside of the
case. You can remove and reglue.

I'll second the loose magnet inside the motor case. You can remove the cover
without removing the motor (two screws in the end). Use an epoxy and do your
best to get the magnet in the same position inside the case. Clean the case
and magnet and use a contact cleaner on the contacts. The contacts control
where/if the wipers stop.

It's not an uncommon problem. The extra heat from the turbo seems to
roast the wiper motors (which are above the exhaust and not far fromt he
catalytic convertor). I've never seen one go bad on a non-Turbo, but
I've replaced the motor on every 240Turbo I or my friends have owned.
You can usually get a used one for $25-35 from a salvage yard that will
continue to work for years unlike fixing the one that's already been
cooked (BTDT). Save yourself the hassle and pick up a salvage motor,
they're a very easy replacement.

To confirm whether or not the motor is the problem, unplug the connector and
check the voltage at the motor when the wipers are on.

To me it sounds like the soul of the relay who controls the wipers has left
the building...
To locate the relay, then remove the carpet in the drivers position. Here
you find a black metal plate which covers the relay. This relay wil fail if
your windshield isn´t tight, and water are comming inside the vehichle.

However, the relay only interrupts the ground contact in the motor to
provide the intermittent function. The high speed, low speed and park
functions are handled by contacts inside the wiper motor.

could be a rusty motor.
mine only worked in high since that provided enough oomph to get it going.
wouldn't work at all in a few weeks.
you can pull the plug to the motor and apply 12V to the various leads to see
if it's the motor or something before it.

Motor always possible, but have you checked the stalk/switch? I've
replaced a couple of those.

I just had a similiar problem, where the wipers only were working in normal
position, and i had to stop them at the right time to get them stop in the
down
position. Changing the relay solved the problem.
