1998 GMC ENVOY wiper blades

Windshield Wipers
You control the windshield wipers by turning the band
with the wiper symbol on
it.
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 wipe. If you want more wipes, 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
LO, the shorter the delay. For steady wiping at
low speed, turn the band away
from you to the
LO position. For high-speed wiping,
turn the band further,
to HI. To stop the wipers, move
the band
to the OFF position.
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
worn or damaged, get new blades or blade inserts.
Windshield Washer
There is a paddle marked with the windshield washer
symbol at the top
of the multifunction lever. To spray
washer fluid on the windshield, push the paddle. The
wipers
will clear the window and then either stop or
return to your preset speed.
In freezing weather, don’t use your washer until
the windshield is warmed. Otherwise the washer
fluid can
form ice on the windshield, blocking
your vision.

The heavier the rain, the harder it is to see. Even if your
windshield wiper blades are
in good shape, a heavy rain
can make
it harder to see road signs and traffic signals,
pavement markings, the edge
of the road and even
people walking.
It’s wise to keep your wiping equipment in good shape
and keep your windshield washer tank filled
with
washer fluid. Replace your windshield wiper inserts
when they show signs
of streaking or missing areas on
the windshield, or when strips of rubber start
to separate
from
the inserts. Driving
too fast through large water puddles or even
going through some car washes can cause problems, too.
The water may affect your brakes. Try to avoid puddles.
But
if you can’t, try to slow down before you hit them.
Wet brakes can cause accidents. They won’t work
as well in a quick stop and may cause pulling to
one side. You could lose control
of the vehicle.
After driving through a large puddle
of water or
a car wash, apply your brake pedal lightly until
your brakes work normally.

Cleaning Glass Surfaces
Glass should be cleaned often. GM Glass Cleaner (GM
Part No. 1050427) or a liquid household glass cleaner
will remove normal tobacco smoke and dust films on
interior glass.
Don’t use abrasive cleaners on glass, because they may
cause scratches. Avoid placing decals on the inside rear
window, since they may have to be scraped off later.
If
abrasive cleaners are used on the inside of the rear
window, an electric defogger element may be damaged.
Any temporary license should not be attached across the
defogger grid.
Cleaning the Outside of the Windshield,
Backglass and Wiper Blades
If the windshield is not clear after using the windshield
washer,
or if the wiper blade chatters when running,
wax, sap or other material may be on the blade
or windshield. Clean
the outside of the windshield with
GM
Windshield Cleaner, Bon Ami@ Powder (non-scratching
glass cleaning powder),
GM Part No. 105001 1. The
windshield is clean
if beads do not form when you rinse
it with water.
Grime from the windshield will stick to the wiper blades
and affect their performance. Clean
the blade by wiping
vigorously with a cloth soaked in full-strength windshield
washer solvent. Then rinse the blade with water.
Check the wiper blades and clean them as necessary;
replace blades that look worn.
Weatherstrips
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth at least every six
months. During very cold, damp weather more frequent
application may be required. (See “Recommended
Fluids and Lubricants” in the Index.)

At Least Twice a Year
Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages are
working properly. Look for any other
loose or damaged
safety belt system parts.
If you see anything that might
keep a safety belt system from doing its
job, have it
repaired. Have any torn or frayed safety belts replaced.
Also look for any opened or broken air bag coverings,
and have them repaired or replaced. (The air bag system
does not need regular maintenance.)
Wiper Blade Check
Inspect wiper blades for wear or cracking. Replace blade
inserts that appear worn or damaged or that streak or
miss areas of the windshield. Also see “Wiper Blades,
Cleaning”
in the Index.

Check the transmission fluid level; add if needed. See
“Automatic Transmission’’ in the Index. A fluid loss
may indicate
a problem. Check the system and repair
if needed.
