GENERAL INFORMATION
INTRODUCTION
An electrically heated rear window defogger is
standard factory-installed equipment on this model.
Electrically heated outside rear view mirrors are an
available factory-installed option on this model. Refer
to 8W-48 - Rear Window Defogger and 8W-62 - Power
Mirrors in Group 8W - Wiring Diagrams for complete
circuit descriptions and diagrams.
REAR WINDOW DEFOGGER SYSTEM
The rear window defogger system will only operate
when the ignition switch is in the On position. When
the defogger switch is in the On position, an electric
heater grid on the rear window glass is energized.
The electric heater grid produces heat to help clear
the rear window glass of ice, snow, or fog.
The defogger system is controlled by a momentary
switch in the rear window switch pod installed in the
instrument panel lower bezel, which also includes the
switch for the rear wiper and washer system. An
amber indicator lamp in the switch pod will light to
indicate when the defogger system is turned on. The
rear window switch pod also contains the defogger
system control circuitry including the timer logic and
the defogger relay.
The defogger system will be automatically turned
off after a programmed time interval of about ten
minutes. After the initial time interval has expired, if
the defogger switch is turned on again during the
same ignition cycle, the defogger system will auto-
matically turn off after about five minutes.
The defogger system will automatically shut off if
the ignition switch is turned to the Off position, or it
can be turned off manually by depressing the defog-
ger switch a second time. Following are general
descriptions of the major components in the defogger

glove box for more information on the features, use
and operation of the defogger system.
HEATED MIRROR SYSTEM
The heated mirror system will only operate when
the ignition switch is in the On position. When the
rear window defogger switch is in the On position, an
electric heater grid located behind the glass of each
of the outside rear view mirrors is energized. When
energized, each of these heater grids produce heat to
help clear the outside rear view mirrors of ice, snow,
or fog.
The heated mirror system is controlled by a momen-
tary rear window defogger switch in the rear window
switch pod installed in the instrument panel lower
bezel, which also includes the switch for the rear wiper
and washer system. An amber indicator lamp in the
switch pod will light to indicate when the defogger sys-
tem is turned on. The rear window switch pod also con-
tains the defogger system control circuitry including the
timer logic and the defogger relay.
The heated mirror system only operates in concert
with the rear defogger system, and will be automat-
ically turned off after a programmed time interval of
about ten minutes. After the initial time interval has
expired, if the defogger switch is turned on again
during the same ignition cycle, the heated mirror
system will automatically turn off after about five
minutes.
The heated mirror system will automatically shut
off if the ignition switch is turned to the Off position,
or it can be turned off manually by depressing the
defogger switch a second time. Following are general
descriptions of the major components in the heated
mirror system. Refer to the owner's manual in the
vehicle glove box for more information on the fea-
tures, use and operation of the heated mirror system.
