WINDSHIELD WIPERS AND WASHERS
The wipers and washers are operated by a switch in the
multifunction lever. Turn the end of the handle to select
the desired wiper speed.
Intermittent Wiper System
The intermittent feature of this system was designed for
use when weather conditions make a single wiping cycle,
with a variable pause between cycles, desirable. For
maximum delay between cycles, rotate the control knob
into the upper end of the delay range.
The delay interval decreases as you rotate the knob until
it enters the low continual speed position. The delay can
be regulated from a maximum of about 15 seconds
between cycles, to a cycle every two seconds. The delay
intervals will double in duration when the vehicle speed
is 10 mph (16 km/h) or less.
