Windshield Washer - GMC 2003 Yukon Owner's Manual

For steady wiping at low speed, turn the band away
from you to the first solid band past the delay settings.
For high-speed wiping, turn the band further, to the
second solid band past the delay settings. To stop the
wipers, move the band to off.
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.
{
CAUTION:
In freezing weather, do not use your washer
until the windshield is warmed. Otherwise the
washer fluid can form ice on the windshield,
blocking your vision.

Rear Window Washer/Wiper
To turn the rear wiper on, turn the control to either
1 or 2. For long delayed wiping, turn the control to 1. For
short delayed wiping, turn the control to 2. To turn the
wiper off, turn the control to 0.
To wash the window, press the knob.
The rear window washer uses the same fluid bottle as
the windshield washer. However, the rear window
washer will run out of fluid before the windshield washer.
If you can wash your windshield but not your rear
windows, check the fluid level.
This control is located on
the instrument panel.
