POWER MIRRORS
DESCRIPTION
If equipped with power mirrors, the control switch
is located on the instrument panel to the left of the
headlamp switch.
OPERATION
The power mirrors are connected to battery feed at
all times. Each mirror head contains two electric
motors, two drive mechanisms, an electric heating
element, and the mirror glass. If the vehicle is
equipped with the optional memory system, each
mirror head also contains both a horizontal and a
vertical motor position sensor. One motor and drive
controls mirror up-and-down movement, and the
other controls right-and-left movement.
An optional driver side outside electrochromic mir-
ror is able to automatically change its reflectance
level. This mirror is controlled by the circuitry of the
automatic day/night inside rear view mirror. A thin
layer of electrochromic material between two pieces
of conductive glass make up the face of the mirror.

INSTALLATION
Two photocell sensors on the inside rear view mirror
are used to monitor light levels and adjust the reflec-
tance of both the inside and driver side outside mir-
rors. This change in reflectance helps to reduce the
glare of headlamps approaching the vehicle from the
rear. (Refer to 8 - ELECTRICAL/POWER MIRRORS/
AUTOMATIC DAY / NIGHT MIRROR - DESCRIP-
TION) for more information on this system.
The motors which operate the mirrors are part of
the mirror assembly and cannot be serviced sepa-
rately.
DIAGNOSIS AND TESTING - POWER MIRRORS
(1) Remove Power Mirror Switch. (Refer to 8 -
ELECTRICAL/POWER MIRRORS/POWER MIRROR
SWITCH - REMOVAL).
(2) Disconnect wiring harness connector to the
power mirror switch and headlamp switch.
(3) Using two jumper wires:
• Connect one to a 12-volt source
• Connect the other to a good body ground
• Refer to the Mirror Test Chart for wire hookups
at the switch connector (Fig. 1).
