vent hole and contaminate the lubricant.
BATTERY WARNING
WARNING: When battery is disconnected, vehicles equipped with
computers may lose memory data. When battery power is
restored, driveability problems may exist on some vehicles.
These vehicles may require a relearn procedure.
WARNING: Batteries produce flammable hydrogen gas. Keep flames and
sparks away from the battery or and explosion may occur.
Never smoke when working in the vicinity of the battery.
WARNING: When checking or servicing the battery, disconnect the
negative cable. Be careful not to cause a short circuit by
allowing metal objects to contact the battery posts and the
vehicle at the same time.
REPLACING BLOWN FUSES
CAUTION: Before replacing a blown fuse, remove ignition key, turn off
all lights and accessories to avoid damaging the electrical
system. Be sure to use fuse with the correct indicated
amperage rating. The use of an incorrect amperage rating fuse
may result in a dangerous electrical system overload.
BRAKE PAD WEAR INDICATOR
Indicator will cause a squealing or scraping noise, warning
that brake pads need replacement.
BRAKE HOSES
WARNING: Worn brake hoses can burst and cause brake failure. If
any sign of cracking, scuffing, or worn spots are found,
replace the brake hoses immediately.
BRAKE FLUID
WARNING: The use of incorrect fluid in the brake system may cause
damage to components. DO NOT use any fluid other than DOT-3
brake fluid. DO NOT use reclaimed fluid or fluid that has
been stored in old or open containers. It is essential that
foreign particles and other liquids are kept out of the
brake fluid reservoir.
CATALYTIC CONVERTER
CAUTION: Continued operation of vehicle with a severe malfunction
could cause converter to overheat, resulting in possible
damage to converter and vehicle.
COOLANT
CAUTION: To avoid possible damage to vehicle use only ethylene-glycol
based coolants with a mixture ratio from 50-70% anti-freeze.
DO NOT use 100% anti-freeze as it will cause the formation
of cooling system deposits.

GENERAL INFORMATION
METRIC CONVERSIONS
METRIC CONVERSIONS
Metric conversions are making life more difficult for the
mechanic. In addition to doubling the number of tools required,
metric-dimensioned nuts and bolts are used alongside English
components in many new vehicles. The mechanic has to decide which tool
to use, slowing down the job. The tool problem can be solved by trial
and error, but some metric conversions aren't so simple. Converting
temperature, lengths or volumes requires a calculator and conversion
charts, or else a very nimble mind. Conversion charts are only part of
the answer though, because they don't help you "think" metric, or
"visualize" what you are converting. The following examples are
intended to help you "see" metric sizes:
LENGTH
Meters are the standard unit of length in the metric system.
The smaller units are 10ths (decimeter), 100ths (centimeter), and
1000ths (millimeter) of a meter. These common examples might help you
to visualize the metric units:
* A meter is slightly longer than a yard (about 40 inches).
* An aspirin tablet is about one centimeter across (.4 inches).
* A millimeter is about the thickness of a dime.
VOLUME
Cubic meters and centimeters are used to measure volume, just
as we normally think of cubic feet and inches. Liquid volume
measurements include the liter and milliliter, like the English quarts
or ounces.
* One teaspoon is about 4 cubic centimeters.
* A liter is about one quart.
* A liter is about 61 cubic inches.
WEIGHT
The metric weight system is based on the gram, with the most
common unit being the kilogram (1000 grams). Our comparable units are
ounces and pounds:
* A kilogram is about 2.2 pounds.
* An ounce is about 28 grams.
TORQUE
Torque is somewhat complicated. The term describes the amount
of effort exerted to turn something. A chosen unit of weight or force
is applied to a lever of standard length. The resulting leverage is
called torque. In our standard system, we use the weight of one pound
applied to a lever a foot long, resulting in the unit called a foot-
pound. A smaller unit is the inch-pound (the lever is one inch long).
Metric units include the meter kilogram (lever one meter long
with a kilogram of weight applied) and the Newton-meter (lever one

1999 ACCESSORIES & EQUIPMENT
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.

POWER MIRROR MOTOR
Caravan, Town & Country, & Voyager
Disconnect harness connector from mirror and headlight
switch. Using 2 jumper wires, connect one jumper to a 12-volt source
and the other jumper wire to a good ground. Connect other end of
jumper wires to specified switch terminals as specified. See POWER

MIRROR MOTOR TEST (DAKOTA, DURANGO, RAM PICKUP, RAM VAN & RAM WAGON)
table, check for open or shorted circuit, or replace mirror assembly
as necessary. See Fig. 3.

POWER MIRROR DEFOGGER
NOTE: On Caravan, Town & Country and Voyager, heated mirror is
controlled by rear window defogger switch. Heated mirror is
on whenever rear window defogger is on.
Caravan, Town & Country, & Voyager
1) Mirror should be warm to touch with rear window defogger
activated. If mirror is not warm to touch, check fuse No. 12 (10-amp)
in junction block. Repair short circuit and replace fuse as necessary.
Check for battery voltage at mirror harness connector Light
Blue/Yellow wire with rear window defogger switch on. If battery
voltage does not exist, repair wiring as necessary. See WIRING
DIAGRAMS. If battery voltage exists, go to next step.
