GMC 1995 Suburban Owner's Manual page 114

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 to the LOW position. For high
speed wiping, turn the band further, to HIGH. To stop the wipers, move the
band to the off symbol.
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 are 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. The windshield wiper motor is
protected from overload by a circuit breaker and a fuse. If the motor
overheats due to heavy snow, etc., the wiper will stop until the motor cools.
Although the circuit is protected from electrical overload, overload due to
heavy snow, etc. may cause wiper linkage damage. Always clear ice and
heavy snow from the windshield before using your windshield wipers.
Windshield Washer
At the top of the lever
there's a paddle with
the word PUSH on it.
To spray washer fluid
on the windshield,
push the paddle.
Washer fluid will spray as long
as
you push the paddle. When you let go of
the paddle, the wipers will continue to wipe for a few seconds and then
either stop or return to the preset speed.
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.
