meter long with force of one Newton applied). Some conversions are:
* A meter kilogram is about 7.2 foot pounds.
* A foot pound is about 1.4 Newton-meters.
* A centimeter kilogram (cmkg) is equal to .9 inch pounds.
PRESSURE
Pressure is another complicated measurement. Pressure is
described as a force or weight applied to a given area. Our common
unit is pounds per square inch. Metric units can be expressed in
several ways. One is the kilogram per square centimeter (kg/cm
).
Another unit of pressure is the Pascal (force of one Newton on an area
of one square meter), which equals about 4 ounces on a square yard.
Since this is a very small amount of pressure, we usually see the
kiloPascal, or kPa (1000 Pascals). Another common automotive term for
pressure is the bar (used by German manufacturers), which equals 10
Pascals. Thoroughly confused? Try the examples below:
* Atmospheric pressure at sea level is about 14.7 psi.
* Atmospheric pressure at sea level is about 1 bar.
* Atmospheric pressure at sea level is about 1 kg/cm
.
* One pound per square inch is about 7 kPa.

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 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.

2) Apply voltage to Light Blue/Yellow wire at heated mirror
and ground Black wire at heated mirror. Mirror should become warm to
touch. If mirror is not warm to touch, remove mirror and test wires
for continuity. If no continuity exists, repair wires. If wires are
okay, replace mirror. To test defogger switch, see appropriate wiring
diagram in REAR WINDOW DEFOGGERS article.
NOTE: On Ram Pickup, heated mirror is controlled by mirror defogger
switch.
Ram Pickup
1) Turn ignition on. While watching instrument panel
voltmeter, turn heated mirror switch on. Voltmeter needle should
deflect. With heated mirror on, mirror should be warm to touch after
3-4 minutes. If system operates as described, system is okay at this
time.
2) If system does not operate as described, go to next step.
Illuminated indicator light means only that voltage exists at heated
mirror relay.
3) Ensure ignition is on. Check fuses in Power Distribution
Center (PDC) and junction block. Ensure fuses are fully seated and
connections are secure. If mirrors are still inoperative, problem is
in heated mirror control, mirror heating grid and/or heated mirror
harness or connectors. If turning switch on causes a large deflection
in instrument panel voltmeter, check for a short circuit in system.
Repair as necessary.

GENERAL INFORMATION
Parasitic Load Explanation & Test Procedures
* PLEASE READ THIS FIRST *
This article is provided for general information only. Not
all procedures apply to all makes and models.
GENERAL INFORMATION
The term Parasitic Load refers to electrical devices that
continue to use or draw current after the ignition switch is turned to
OFF position. This small amount of continuous battery draw is
expressed in milliamps (mA). On Ford Motor Co. and General Motors
vehicles produced after 1980, a typical Parasitic Load should be no
more than 50 milliamps (0.050 amps).
Vehicles produced since 1980 have memory devices that draw
current with ignition off for as long as 20 minutes before shutting
down the Parasitic Drain. When Parasitic Load exceeds normal
specifications, the vehicle may exhibit dead battery and no-start
condition.
Follow test procedure for checking Parasitic Loads to
completion. A brief overview of a suggested test procedure is included
along with some typical Parasitic Load specifications. Refer to the
GENERAL MOTORS PARASITIC LOAD TABLE chart.
TESTING FOR PARASITIC LOAD
INTRODUCTION
CAUTION: Always turn ignition off when connecting or disconnecting
battery cables, battery chargers or jumper cables. DO NOT
turn test switch to OFF position (which causes current to run
through ammeter or vehicle electrical system).
NOTE: Memory functions of various accessories must be reset after
the battery is reconnected.
The battery circuit must be opened to connect test switch
(shunt) and ammeter into the circuit. When a battery cable is removed,\
timer circuits within the vehicle computer are interrupted and
immediately begin to discharge. If in doubt about the condition of the
ammeter fuse, test it with an ohmmeter prior to beginning test. An
open fuse will show the same reading (00.00) as no parasitic drain.
Begin test sequence with the meter installed and on the 10-amp scale.
Select lower scale to read parasitic draw.
TEST PROCEDURE USING TEST SWITCH
1) Turn ignition off. Remove negative battery terminal cable.
Install Disconnect Tool (J-38758) test switch male end to negative
battery cable. Turn test switch knob to OFF position (current through
meter). Install negative battery cable to the female end of test
switch.
2) Turn test switch knob to ON position (current through
switch). Road test vehicle with vehicle accessories on (radio, air
conditioner, etc.). After road test, turn ignition switch to LOCKED
position and remove key. Connect ammeter terminals to test switch
