Dodge Durango (DN). Manual — part 318

POWER MIRROR SWITCH

Both the right and left power outside mirrors are

controlled by a single multi-function switch unit
located on and mounted to the upper flag area of the
driver side door trim panel. The switch knob is
rotated clockwise (right mirror control), or counter-
clockwise (left mirror control) to select the mirror to
be adjusted. The switch knob is then moved in a joy-
stick fashion to control movement of the selected mir-
ror up, down, right, or left.

The power mirror switch cannot be repaired and, if

faulty or damaged, it must be replaced. The power
mirror switch knob is available for service replace-
ment.

DIAGNOSIS AND TESTING

POWER MIRROR SYSTEM

For circuit descriptions and diagrams, refer to

8W-62 - Power Mirrors in Group 8W - Wiring Dia-
grams.

(1) Check the fuses in the Power Distribution Cen-

ter (PDC) and the junction block. If OK, go to Step 2.
If not OK, repair the shorted circuit or component as
required and replace the faulty fuse(s).

(2) Check for battery voltage at the fuse in the

junction block. If OK, go to Step 3. If not OK, repair
the open circuit to the PDC as required.

(3) Disconnect and isolate the battery negative

cable. Remove the driver side door trim panel and
unplug the wire harness connector from the power
mirror switch. Connect the battery negative cable.
Check for battery voltage at the fused B(+) circuit
cavity in the door wire harness half of the power mir-
ror switch wire harness connector. If OK, go to Step
4. If not OK, repair the open circuit to the junction
block as required.

(4) Disconnect and isolate the battery negative

cable. Check for continuity between the ground cir-
cuit cavity in the door wire harness half of the power
mirror switch wire harness connector and a good
ground. There should be continuity. If OK, go to Step
5. If not OK, repair the circuit to ground as required.

(5) If the problem being diagnosed is an inopera-

tive power mirror electric heating grid, proceed as
follows. If not, go to Step 8. Disconnect and isolate
the battery negative cable. Remove the front door
trim panel on the side of the vehicle with the inoper-
ative mirror heating grid. Unplug the wire harness
connector at the mirror. Check for continuity between
the ground circuit cavity in the body half of the
power mirror wire harness connector and a good
ground. If OK, go to Step 6. If not OK, repair the
open circuit to ground as required.

(6) Connect the battery negative cable. Turn the

ignition switch to the On position. Turn on the rear
window defogger system. Check for battery voltage at
the rear window defogger relay output circuit cavity
in the body half of the power mirror wire harness
connector. If OK, go to Step 7. If not OK, repair the
open circuit to the rear window defogger relay as
required.

(7) Check for continuity between the ground cir-

cuit and the rear window defogger relay output cir-
cuit cavities in the mirror half of the power mirror
wire harness connector. There should be continuity. If
not OK, replace the faulty power mirror. If OK, check
the resistance through the electric heating grid cir-
cuit (Fig. 1). Correct resistance through the electric
heating grid should be from 6 to 8.2 ohms when mea-
sured at an ambient temperature of 21° C (70° F). If
not OK, replace the faulty power mirror.

(8) Check the power mirror switch continuity as

shown in (Fig. 2). If OK, go to Step 9. If not OK,
replace the faulty switch.

(9) Unplug the wire harness connector at the inop-

erative power mirror. Use two jumper wires, one con-
nected to a 12-volt battery feed, and the other
connected to a good body ground. See the Power Mir-
ror Test chart for the correct jumper wire connections
to the power mirror half of the power mirror wire
harness connector (Fig. 3). If the power mirror(s) do
not respond as indicated in the chart, replace the
faulty power mirror assembly. If the power mirror(s)
do respond as indicated in the chart, repair the cir-

GENERAL INFORMATION

INTRODUCTION

An automatic dimming inside day/night rear view

mirror is an available factory-installed option on this
model. Refer to 8W-44 - Interior Lighting in Group
8W - Wiring Diagrams for complete circuit descrip-
tions and diagrams.

AUTOMATIC DAY/NIGHT MIRROR SYSTEM

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.

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.

Following is a general description of the automatic

day/night mirror. Refer to the owner’s manual in the
vehicle glove box for more information on the fea-
tures, use and operation of the automatic day/night
mirror system.

DESCRIPTION AND OPERATION

AUTOMATIC DAY/NIGHT MIRROR

The automatic day/night mirror uses a thin layer

of electrochromic material between two pieces of con-
ductive glass to make up the face of the mirror.
When the mirror switch is in the On position, two
photocell sensors are used by the mirror circuitry to
monitor external light levels and adjust the reflec-
tance of the mirror.

The ambient photocell sensor is located on the for-

ward-facing (windshield side) of the rear view mirror
housing, and detects the ambient light levels outside
of the vehicle. The headlamp photocell sensor is
located inside the rear view mirror housing behind
the mirror glass and faces rearward, to detect the
level of the light being received at the rear window
side of the mirror. When the circuitry of the auto-
matic day/night mirror detects that the difference
between the two light levels is too great (the light
level received at the rear of the mirror is much
higher than that at the front of the mirror), it begins
to darken the mirror.

The automatic day/night mirror circuitry also mon-

itors the transmission using an input from the
backup lamp circuit. The mirror circuitry is pro-
grammed to automatically disable its self-dimming
feature whenever it senses that the transmission
backup lamp circuit is energized.

The automatic day/night mirror is a completely

self-contained unit and cannot be repaired. If faulty
or damaged, the entire mirror assembly must be
replaced.

DIAGNOSIS AND TESTING

grams.

(1) Check the fuse in the junction block. If OK, go

to Step 2. If not OK, repair the shorted circuit or
component as required and replace the faulty fuse.

(2) Turn the ignition switch to the On position.
