GENERAL INFORMATION
INTRODUCTION
Power operated or power operated and heated out-
side rear view mirrors are available factory-installed
options on this model. Refer to 8W-62 - Power Mir-
rors in Group 8W - Wiring Diagrams for complete cir-
cuit descriptions and diagrams.
NOTE: This group covers both Left-Hand Drive
(LHD) and Right-Hand Drive (RHD) versions of this
model. Whenever required and feasible, the RHD
versions of affected vehicle components have been
constructed as mirror-image of the LHD versions.
While most of the illustrations used in this group
represent only the LHD version, the diagnostic and
service
procedures
outlined
can
generally
be
applied to either version. Exceptions to this rule
have been clearly identified as LHD or RHD, if a
special illustration or procedure is required.
POWER MIRROR SYSTEM
The power operated or power operated and heated
outside rear view mirrors allow the driver to adjust
both outside mirrors electrically from the driver seat
position by operating a switch on the driver side
front door trim panel. The power mirrors receive bat-
tery current through a fuse in the junction block, and
will only operate when the ignition switch is in the
On or Accessory positions.
The heated mirror option includes an electric heat-
ing grid behind the mirror glass in each outside mir-
ror, which can clear the mirror glass of ice, snow, or
fog. The heating grid receives fused battery current
through the rear window defogger relay only when
the rear window defogger system is turned on. Refer
to Group 8N - Electrically Heated Systems for more
information on the rear window defogger system.
Following are general descriptions of the major
components in the power mirror system. Refer to the
owner’s manual in the vehicle glove box for more
information on the features, use and operation of the
power mirror system.
DESCRIPTION AND OPERATION
POWER MIRROR
Each power mirror head contains two electric
motors, two drive mechanisms, and the mirror glass.
One motor and drive controls mirror up-and-down
movement, and the other controls right-and-left
movement.
The power mirrors in vehicles equipped with the
available heated mirror option also include an elec-
tric heating grid located behind the mirror glass.
This heating grid is energized by the rear window
defogger relay whenever the rear window defogger
system is turned on. Refer to Group 8N - Electrically
Heated Systems for more information on the opera-
tion of the rear window defogger system.
The power mirror assembly cannot be repaired.
Only the mirror glass is serviced separately. If any
other component of the power mirror unit is faulty or
damaged, the entire assembly must be replaced.
POWER MIRROR SWITCH
Both the right and left power outside mirrors are
controlled by a single multi-function switch unit
located on the driver side front door trim panel. Two
versions of this switch are offered. Models without
power windows or power locks have a stand-alone
switch mounted in the driver side front door trim
panel. Models equipped with power windows and
power locks have a power mirror switch that is inte-
gral to the Driver Door Module (DDM).
Both versions of the switch are operated in the
same manner. A three position rocker-type mirror
