Buick 1994 LeSabre Owner's Manual page 93

You control the windshield wipers by turning the band
marked "WIPER."
For a single wiping cycle, turn the band to "MIST."
Hold it there until the wipers start, then let go. The
wipers will stop after one cycle. If you want more
cycles, hold the band on "MIST" longer.
You can set the wiper speed for a long or short delay
between wipes. This can be very useful in light rain or
snow. Turn the band to choose the delay time. The
closer to "LOW," the shorter the delay.
For steady wiping at low speed, turn the band away
from you to the "LOW" position. For high speed
wiping, turn the band further, to "HIGH." To stop the
wipers, move the band to "OFF."
Remember that damaged wiper blades may prevent you
from seeing well enough to drive safely. To avoid
damage, be sure to clear ice and snow from the wiper
blades
before
using
them. If they're frozen to
the
windshield, carefully loosen or thaw them. If your
blades do become damaged, get new blades or blade
inserts.
Heavy snow or ice can overload your wipers. A circuit
breaker will stop them until the motor cools. Clear away
snow or ice to prevent an overload.
Windshield Washer
At the top of the multifunction lever there's a paddle
with the word "PUSH" on it. To spray washer fluid on
the windshield, push the paddle for less than a second.
The washer will spray several times, then stop. Unless
they are already turned on, the wipers will operate at
low speed for several sweeps, then turn off.
To get more fluid on the windshield, push and hold the
paddle. Spraying will continue as long as the paddle is
held.
Driving without washer fluid can be dangerous. A bad
mud splash can block your vision. You could hit another
vehicle or go off the road. Check your washer fluid level
often.
