CHRY - Power Mirrors
Caravan, Dakota, Durango, Ram Pickup, Ram Van, Ram Wagon,
Town & Country, & Voyager
DESCRIPTION
Outside power rear view mirrors consist of door-mounted
mirrors with internal motor drive and backing plate. On Caravan, Town
& Country, and Voyager, mirrors are controlled by a rocker switch for
left or right mirror selection and a platform button for up, down,
right and left movement. On Dakota, Durango, Ram Pickup, Ram Van and
Ram Wagon, mirrors are controlled by a single, multifunction,
joystick-type switch assembly. On all models, mirror motors are
integral with mirror assemblies and cannot be serviced separately. On
Dakota and Durango, fold-away rear view mirrors are optional.
Dakota, Durango and Ram Pickup are equipped with an automatic
dimming day/night inside mirror. The mirror uses 2 photocell sensors
to monitor ambient and rear facing light levels. The mirror
automatically adjusts its reflectance to reduce headlight glare from
vehicles approaching from the rear. The mirror is controlled by an
off/on switch located on the mirror bottom.
Caravan, Ram Pickup, Town & Country and Voyager have optional
heated outside mirrors. On Caravan, Town & Country and Voyager, heated
mirror is activated whenever the rear defogger is on. On Ram Pickup,
heated mirror is activated by switch in dash. A timer turns off mirror
heater after about 10 minutes.
COMPONENT TESTS
AUTOMATIC DAY/NIGHT INSIDE MIRROR
1) Turn ignition switch to ON position with transmission in
Neutral or Park. Place mirror switch in ON position (switch LED
illuminated). Cover forward facing sensor with a dark cloth or tape to
exclude any ambient light. See Fig. 1.
2) Shine a light into rear-facing sensor. Observe whether or
not mirror darkens. With mirror darkened, place transmission in
Reverse. Mirror should return to normal. If conditions of steps 1) and
2) are met, mirror is operating correctly. If conditions are not met,
go to next step.
3) Turn ignition on. Check for battery voltage at fuse No. 11
in junction block. If battery voltage exists on both sides of fuse, go
to next step. If battery voltage does not exist, repair circuit to
junction block. See WIRING DIAGRAMS. If fuse is blown, repair short
circuit and replace fuse.
4) Check for battery voltage at day/night mirror wire
connector terminal No. 1 (Dark Blue/White wire). If battery voltage
exists, go to next step. If battery voltage does not exist, repair
open circuit between mirror and junction block.
5) Check for continuity between ground and day/night mirror
wire connector terminal No. 2 (Black wire). If continuity exists, go
to next step. If continuity does not exist, repair open ground
circuit.
6) Check for battery voltage at day/night mirror wire
connector terminal No. 3 (Violet/Black wire) with transmission in
Reverse. If battery voltage exists, replace mirror. If battery voltage
does not exist, check back-up light circuit. See WIRING DIAGRAMS.
