GMC 1998 Yukon - Rear Window Defogger

Rear Window Defogger (If Equipped)
If you see lines running across the rear window, you
have a rear window defogger. The lines warm the glass.
To turn on the rear window
defogger, press this button
next to the
fan control knob.
The rear window defogger
will only work
if the
igllition switch is turned
to RUN. For best results,
first clear the window of

ice
as possible.
The defogger
will shut itself off after several minutes. If
you need additional warming time, press the button
again.
You can turn the defogger off at any time by
pressing the button.
If your vehicle is equipped with the optional heated
outside rearview mirrors, the rear window defogger
button will activate the. rear window defogger and the
heated outside rearview mirrors.
Do not attach
a temporary vehicle license, tape or decals
across the defogger grid on the rear window.
