squeaking windshield wiper - too much arm tension?

I tested this out and found that both sides are squeaking. So since it's
both, I suppose the tension isn't the culprit. It IS a rubber/glass squeak,
not metal.

With the wipers running in intermittent mode, there are three defined
squeaks occurring: one when the wiper starts to lift, one when it reaches
its furthest most point to the left and turns around, and one when it
reaches its resting point.

Now, here's another clue: why does it NOT squeak during the first 30 seconds
of operation? The rains starts, I start up the wipers when they become
needed, the wipers are working for about 30 seconds.... and then the
squeaking begins. What might that be telling me? Smartass suggestions are
allowed. Hell, I give 'em, I can take 'em.

Unfortunately, ONCE in a while I'm the latter.

I haven't tried that yet. "Unfortuntately" it doesn't rain here very often,
though lately we're doing quite well in that department. Translation: I
don't know when I'll get another chance for this. I should keep a bottle of
windex and a roll of paper towels in the car.

No, none at all.
