DAY/NIGHT INSIDE MIRROR
POWER MIRRORS
DESCRIPTION
AUTOMATIC DAY/NIGHT MIRROR
The automatic day/night mirror system is able to
automatically change the reflectance of the inside
rear view mirror in order to reduce the glare of head-
lamps approaching the vehicle from the rear. The
automatic day/night rear view mirror receives bat-
tery current through a fuse in the junction block only
when the ignition switch is in the ON position.
OUTSIDE REAR VIEW MIRROR
The power operated outside rear view mirrors
allow the driver to adjust both outside mirrors elec-
trically from the driver side front seat position by
operating a switch on the driver side front door trim
panel.
OPERATION
AUTOMATIC DAY/NIGHT MIRROR
A switch located on the bottom of the automatic
day/night mirror housing allows the vehicle operator
to select whether the automatic dimming feature is
operational. When the automatic day/night mirror is
turned on, the mirror switch is lighted by an integral
Light-Emitting Diode (LED). The mirror will auto-
matically disable its self-dimming feature whenever
the vehicle is being driven in reverse.
Refer to the owner's manual for more information
on the features, use and operation of the automatic
day/night mirror system.

The power mirrors receive a non-switched battery
feed through a fuse in the junction block so that the
system will remain operational, regardless of the
ignition switch position.
DIAGNOSIS AND TESTING - POWER MIRRORS
WIRING VOLTAGE TEST
The following wiring test determines whether or
not voltage is continuous through the body harness
to switch.
(1) Remove the power mirror switch.
(2) Disconnect wire harness connector from back of
power mirror switch.
(3) Connect the clip end of a 12 volt test light to
Pin 11 in the mirror switch harness connector. Touch
the test light probe to Pin 9.
If the test light illuminates, the wiring circuit
between the battery and switch is OK.
If the lamp does not illuminate, first check fuse in
the Junction Block (JB). If circuit breaker is OK,
then check for a broken wire.
Refer to the appropriate wiring information. The
wiring information includes wiring diagrams, proper
wire and connector repair procedures, details of wire
harness routing and retention, connector pin-out
information and location views for the various wire
harness connectors, splices and grounds.
SIDE REPEATER LAMP TEST
Some vehicles are equipped with side repeater
lamps integral to the sideview mirror. If the LED's
within the mirror do not operate and the other
within the system do, proceed with the side repeater
lamp test. Refer to the appropriate wiring informa-
tion. The wiring information includes wiring dia-
