Headlamp Washer - GMC 2007 Envoy Denali Owner's Manual

To turn the rear wiper on, turn the control to
either 1, 2, or 3. For delayed wiping, turn the
control to 1 or 2. For steady wiping, turn the control
to 3. To turn the wiper off, turn the control to 0.
To wash the rear window, press the washer
symbol located in the center of the control.
The rear window washer uses the fluid from the
same reservoir as the windshield washer.
However, the rear window washer runs out of fluid
before the windshield washer. If you can wash
your windshield but not your rear window, check
the fluid level.
The rear window/washer
control is located to
the right of the
steering wheel on the
instrument panel.
