Windshield Wipers And Washer - Ford Windstar Owner's Manual

Windshield Wipers and Washer

Variable Interval Wipers
Your vehicle has wipers that operate at varying intervals. For
example, you can set the interval so they wipe less often in
light rain or more often in heavier rain. The wiper delays range
from about 1.5 to 20 seconds.
Variable interval wiper control
To set the interval wipers, rotate the knob at the end of the turn
signal lever to the most effective interval. The farther the knob
is from the OFF position, the faster the wipers move.
Speed Dependent Wipers
This feature compensates for the extra moisture that
accumulates on your windshield at higher speeds during rain.
At higher speeds, the Speed Dependent feature shortens the
delay between wipes when you use the variable interval wipers.
Delay will automatically adjust at speeds between 10 and
65 mph (16 and 105 km/h).
The Speed Dependent feature comes disabled from the factory,
but can be activated at any time by using the following
procedure.
