light CHRYSLER VOYAGER 1996 Service Manual

SERVICE PROCEDURES
WHEEL INSTALLATION
To install the wheel, first position it properly on
the mounting surface of the hub using the hub pilot
as a guide. All wheel nuts should be lightly tightened
before progressively tightening them in the proper
sequence (Fig. 7). Then fully tighten the wheel nuts
in the proper sequence (Fig. 7) to a torque of 135
N´m (100 ft. lbs.). Never use oil or grease on studs or
nuts.
TIRE AND WHEEL BALANCE
Balancing need is indicated by vibration of seats,
floor pan, or steering wheel. The vibration will be
noticed mostly when driving over 90 km/h (55 mph)
on a smooth road.
It is recommended that a two plane dynamic bal-
ancer be used when a wheel and tire assembly
require balancing. Static balancing should be used
only when a two plane balancer is not available.
Off-vehicle tire and wheel balancing is recom-
mended to be used on this vehicle.
NOTE: If on vehicle equipment is being used to bal-
ance the tire /wheel assemblies, remove the oppo-
site tire/wheel from the vehicle.
For static balancing, find the location of heavy spot
on tire/wheel causing the imbalance. Counter balance
wheel directly opposite the heavy spot. Determine
weight required to counterbalance the area of imbal-
ance. Place half of this weight on theinnerrim
flange and the other half on theouterrim flange
(Fig. 8).
For dynamic balancing, the balancing equipment is
designed to indicate the location and amount of
weight to be applied to both the inner and outer rim
flanges (Fig. 9).

GENERAL INFORMATION
PAINT CODE
A paint code is provided on the body code plate
located in the engine compartment. Refer to the
Introduction section at the front of this manual for
body code plate description. The paint and trim codes
are also included on the Vehicle Safety Label located
on the driver's door end frame.
BASE COAT/CLEAR COAT FINISH
On most vehicles a two-part paint application (base
coat/clear coat) is used. Color paint that is applied to
primer is called base coat. The clear coat protects the
base coat from ultraviolet light and provides a dura-
ble high-gloss finish.
WET SANDING, BUFFING, AND POLISHING
Minor acid etching, orange peel, or smudging in
clear coat or single-stage finishes can be reduced
with light wet sanding, hand buffing, and polishing.
If the finish has been wet sanded in the past, it
cannot be repeated. Wet sanding operation
should be performed by a trained automotive
paint technician.
CAUTION: Do not remove clear coat finish, if
equipped. Base coat paint must retain clear coat for
durability.
PAINTED SURFACE TOUCH-UP
When a painted metal surface has been scratched
or chipped, it should be touched-up as soon as possi-
ble to avoid corrosion. For best results, use Mopart
Scratch Filler/Primer, Touch-Up Paints and Clear Top
Coat. Refer to Introduction group of this manual for
Body Code Plate information.
TOUCH-UP PROCEDURE
(1) Scrape loose paint and corrosion from inside
scratch or chip.
(2) Clean affected area with MopartTar/Road Oil
Remover, and allow to dry.
(3) Fill the inside of the scratch or chip with a coat
of filler/primer. Do not overlap primer onto good sur-
face finish. The applicator brush should be wet
enough to puddle-fill the defect without running. Do
not stroke brush applicator on body surface. Allow
the filler/primer to dry hard.
(4) Cover the filler/primer with color touch-up
paint. Do not overlap touch-up color onto the original
color coat around the scratch or chip. Butt the new
color to the original color, if possible. Do not stroke
applicator brush on body surface. Allow touch-up
paint to dry hard.
(5) On vehicles without clear coat, the touch-up
color can be lightly wet sanded (1500 grit) and pol-
ished with rubbing compound.
(6) On vehicles with clear coat, apply clear top coat
to touch-up paint with the same technique as
described in Step 4. Allow clear top coat to dry hard.
If desired, Step 5 can be performed on clear top coat.

DIAGNOSIS AND TESTING
WATER LEAKS
Water leaks can be caused by poor sealing,
improper body component alignment, body seam
porosity, missing plugs, or blocked drain holes. Cen-
trifugal and gravitational force can cause water to
drip from a location away from the actual leak point,
making leak detection difficult. All body sealing
points should be water tight in normal wet-driving
conditions. Water flowing downward from the front of
the vehicle should not enter the passenger or luggage
compartment. Moving sealing surfaces will not
always seal water tight under all conditions. At
times, side glass or door seals will allow water to
enter the passenger compartment during high pres-
sure washing or hard driving rain (severe) condi-
tions. Overcompensating on door or glass
adjustments to stop a water leak that occurs under
severe conditions can cause premature seal wear and
excessive closing or latching effort. After completing
a repair, water-test vehicle to verify leak has stopped
before returning vehicle to use.
VISUAL INSPECTION BEFORE WATER LEAK
TESTS
Verify that floor and body plugs are in place, body
drains are clear, and body components are properly
aligned and sealed. If component alignment or seal-
ing is necessary, refer to the appropriate section of
this group for proper procedures.
WATER LEAK TESTS
WARNING: DO NOT USE ELECTRIC SHOP LIGHTS
OR TOOLS IN WATER TEST AREA. PERSONAL
INJURY CAN RESULT.When the conditions causing a water leak have
been determined, simulate the conditions as closely
as possible.
²If a leak occurs with the vehicle parked in a
steady light rain, flood the leak area with an open-
ended garden hose.
²If a leak occurs while driving at highway speeds
in a steady rain, test the leak area with a reasonable
velocity stream or fan spray of water. Direct the
spray in a direction comparable to actual conditions.
²If a leak occurs when the vehicle is parked on an
incline, hoist the end or side of the vehicle to simu-
late this condition. This method can be used when
the leak occurs when the vehicle accelerates, stops or
turns. If the leak occurs on acceleration, hoist the
front of the vehicle. If the leak occurs when braking,
hoist the back of the vehicle. If the leak occurs on left
turns, hoist the left side of the vehicle. If the leak
occurs on right turns, hoist the right side of the vehi-
cle. For hoisting recommendations refer to Group 0,
Lubrication and Maintenance, General Information
section.
WATER LEAK DETECTION
To detect a water leak point-of-entry, do a water
test and watch for water tracks or droplets forming
on the inside of the vehicle. If necessary, remove inte-
rior trim covers or panels to gain visual access to the
leak area. If the hose cannot be positioned without
being held, have someone help do the water test.
NSBODY 23 - 23

Some water leaks must be tested for a considerable
length of time to become apparent. When a leak
appears, find the highest point of the water track or
drop. The highest point usually will show the point of
entry. After leak point has been found, repair the
leak and water test to verify that the leak has
stopped.
Locating the entry point of water that is leaking
into a cavity between panels can be difficult. The
trapped water may splash or run from the cavity,
often at a distance from the entry point. Most water
leaks of this type become apparent after accelerating,
stopping, turning, or when on an incline.
MIRROR INSPECTION METHOD
When a leak point area is visually obstructed, use
a suitable mirror to gain visual access. A mirror can
also be used to deflect light to a limited-access area
to assist in locating a leak point.
BRIGHT LIGHT LEAK TEST METHOD
Some water leaks in the luggage compartment can
be detected without water testing. Position the vehi-
cle in a brightly lit area. From inside the darkened
luggage compartment inspect around seals and body
seams. If necessary, have a helper direct a drop light
over the suspected leak areas around the luggage
compartment. If light is visible through a normally
sealed location, water could enter through the open-
ing.
PRESSURIZED LEAK TEST METHOD
When a water leak into the passenger compart-
ment cannot be detected by water testing, pressurize
the passenger compartment and soap test exterior of
the vehicle. To pressurize the passenger compart-
ment, close all doors and windows, start engine, and
set heater control to high blower in HEAT position. If
engine can not be started, connect a charger to the
battery to ensure adequate voltage to the blower.
With interior pressurized, apply dish detergent solu-
tion to suspected leak area on the exterior of the
vehicle. Apply detergent solution with spray device or
soft bristle brush. If soap bubbles occur at a body
seam, joint, seal or gasket, the leak entry point could
be at that location.
WIND NOISE
Wind noise is the result of most air leaks. Air leaks
can be caused by poor sealing, improper body compo-
nent alignment, body seam porosity, or missing plugs
in the engine compartment or door hinge pillar areas.
All body sealing points should be airtight in normal
driving conditions. Moving sealing surfaces will not
always seal airtight under all conditions. At times,
side glass or door seals will allow wind noise to be
noticed in the passenger compartment during highcrosswinds. Over compensating on door or glass
adjustments to stop wind noise that occurs under
severe conditions can cause premature seal wear and
excessive closing or latching effort. After a repair pro-
cedure has been performed, test vehicle to verify
noise has stopped before returning vehicle to use.
Wind noise can also be caused by improperly fitted
exterior moldings or body ornamentation. Loose
moldings can flutter, creating a buzzing or chattering
noise. An open cavity or protruding edge can create a
whistling or howling noise. Inspect the exterior of the
vehicle to verify that these conditions do not exist.
VISUAL INSPECTION BEFORE TESTS
Verify that floor and body plugs are in place and
body components are aligned and sealed. If component
alignment or sealing is necessary, refer to the appro-
priate section of this group for proper procedures.
ROAD TESTING WIND NOISE
(1) Drive the vehicle to verify the general location
of the wind noise.
(2) Apply 50 mm (2 in.) masking tape in 150 mm
(6 in.) lengths along weatherstrips, weld seams or
moldings. After each length is applied, drive the vehi-
cle. If noise goes away after a piece of tape is applied,
remove tape, locate, and repair defect.
POSSIBLE CAUSE OF WIND NOISE
²Moldings standing away from body surface can
catch wind and whistle.
²Gaps in sealed areas behind overhanging body
flanges can cause wind-rushing sounds.
²Misaligned movable components.
²Missing or improperly installed plugs in pillars.
²Weld burn through holes.
SERVICE PROCEDURES
HEAT STAKING
(1) Remove trim panel.
(2) Bend or move the trim panel components at

(3) Heat stake the components.
(a) If the heat staked or component seam loca-
tion is loose, hold the two components tightly
together and using a soldering gun with a flat tip,
melt the material securing the components
together. Do not over heat the affected area, dam-
age to the exterior of the trim panel may occur.
(b) If the heat staked material is broken or miss-
ing, use a hot glue gun to apply new material to
the area to be repaired. The panels that are being
heat staked must be held together while the apply-
ing the glue. Once the new material is in place, it

DIAGNOSTICS
During the Actuator calibration, diagnostics are
performed on the actuators and evaporator tempera-
ture Fin Sensor. Once diagnostics are completed the
REAR WIPER and INTERMITTENT LED's will flash
to indicate either a successful calibration or the
appropriate fail code(s). At this time manual testing
of the Blend, Mode and Driver (if equipped) potenti-
ometers can be performed. If a failure is detected
during Diagnostics a fault will be set in the control.
When Ignition is cycled OFF and then ON or Diag-
nostics is aborted, the REAR WIPER and INTER-
MITTENT LED's will flash simultaneously showing
that a failure has occurred. The control will not indi-
cate the fail code, but only that a failure had
occurred during the last diagnostics test. The only
way to clear the failure codes is repeat the Calibra-
tion Diagnostic and Cooldown test, after all repairs
are completed.
COOLDOWN TEST
This test has been designed for performance test-
ing of the A/C system at the manufacturing facility. If
the HVAC control module is replaced, the Cooldown
test will occur during Calibration test. Cooldown will
not occur on Heater Only units. During the Cooldown
test the control will monitor the temperature of the
Fin Sensor. The A/C system must be able to bring the
evaporator temperature down a predetermined mini-
mum amount in less than 2 minutes.
CALIBRATION/COOLDOWN LED DISPLAY
CODES
See table for definition of flashing LED's. If no
problems are found, the control functions normally.

(5) Once repairs are completed repeat the Calibra-
tion Diagnostic and Cooldown test. Repeating the
test is necessary to clear the fault codes.
After calibration, Rear Wiper LED flashing
once, Intermittent LED flashing nine times.
The HVAC control module, has a internal
failure.
(1) Replace the HVAC control module.
(2) Once repairs are completed repeat the Calibra-
tion Diagnostic and Cooldown test. Repeating the
test is necessary to clear the fault codes.
After calibration and testing the A/C and
RECIRC LED flashing simultaneously. Failed
Cooldown test.
(1) Determine if the refrigerant system is operat-
ing correctly:
²Check the outlet air temperature
²Feel the compressor suction plumbing, is it hot?
(2) If not OK, go to Step 3. If OK, repeat the Cal-
ibration Diagnostic and Cooldown test.
(3) If system does not seem to be operating cor-
rectly, perform diagnostics for poor performance:
²Low refrigerant charge
²No charge
²Compressor not operating
Verify that the test was done with the evaporator
at room temperature. The test consists of starting
the compressor and measuring the time it takes for
the evaporator temperature to fall 7ÉC (20ÉF). If the
compressor has been running, the evaporator is cold
already and will not be capable of falling 7ÉC (20ÉF).
If the test was run with a cold evaporator, turn A/C
off and turn the blower motor switch to high position
for 3 to 5 minutes till the evaporator is to room tem-
perature. Then repeat the Calibration Diagnostic and
Cooldown test.
If refrigerant system is performing properly and
the system will not pass test. Repeat the Calibration
Diagnostic and Cooldown test to determine if the
evaporator temperature FIN sensor has developed an
open or a short circuit. If the HVAC control module
still passes Calibration test, verify Cooldown test
manually with a pocket thermometer. The outlet air
temperature must drop at least 7ÉC (20ÉF) within
two minutes. If the vehicle passes with the manual
thermometer, take HVAC control to level 4 (evapora-
tor probe temperature readout) and repeat the
Cooldown test. Ensure the evaporator is at room tem-
perature before starting test. Check if evaporator
