Actually, I think that the wind DOES affect it. Wind chill is just a
subjective
assessment of how cold it 'feels', and doesn't apply as such. 1 degree is
still
1 degree. But I've found that one windy cold nights my washers would freeze
up right at the spray nozzles. Same thing on the highway on really cold
days. Sometimes I could get them unfrozen by just pressing my thumb right
on the
nozzle. Other times the ice would be back up to an inch in the hose.
The only thing I can figure is that the wind hastens the evaporation of the
alcohol in the fluid near the tip, and the freezing point depression from
the
alcohol in the solution is lost. Granted, this is not a major problem, and
seems
to be dependant on the brand and type of washer fluid.
Not that it would help in this case, but back in high school I saw a washer
warmer setup. It was just an extra piece of hose you spliced into the
washer
line. You took the hose to the heater core line and wrapped it around it.
If
you were drawing heat into the passenger compartment, then the heater line
would get warm, and the washer fluid would get warm as well. I never used
it though, so I don't know how well it worked.
