gage compartment. If light is visible through a nor-
mally sealed location, water could enter through the
opening.
PRESSURIZED LEAK TEST METHOD
When a water leak into the passenger compartment
can not be detected by water testing, pressurize the
passenger compartment and soap test exterior of the
vehicle. To pressurize the passenger compartment,
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 assure adequate voltage to the blower. With
interior pressurized, apply dish detergent solution 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 air tight in normal
driving conditions. Moving sealing surfaces will not
always seal air tight under all conditions. At times,
side glass, door, or convertible top seals will allow wind
noise to be noticed in the passenger compartment
during high cross-winds. Over compensating on door,
glass, or top adjustments to stop wind noise that occurs
under severe conditions, can cause premature seal
wear and excessive closing or latching effort. After a repair procedure has been performed, test vehicle to
verify leak has stopped before returning vehicle to use. Wind noise can also be caused by improperly fitted
exterior mouldings or body ornamentation. Loose
mouldings can flutter, creating a buzzing or chattering
noise. An open cavity or protruding edge can create
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, body
drains are clear and body components are aligned and
sealed. If component alignment or sealing is necessary,
refer to the appropriate 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 moul-
dings. After each length is applied drive vehicle. If
noise goes away after a piece of tape is applied, remove
tape, locate and repair defect.
POSSIBLE CAUSE OF WIND NOISE
² Mouldings standing away from body surface can
catch wind and whistle.
² Gaps in sealed areas behind overhanging body
flanges can cause wind rushing sounds.
² Misaligned movable components.
² Missing or improperly installed plugs in pillars.
² Weld burn through holes.

PAINT
INTRODUCTION
A paint code is provided on the body code plate
located in the engine compartment. Refer to the Intro-
duction section at the front of this manual for body code
plate description. The color names provided in the
Paint and Trim Code Description chart are the color
names used on most repair product containers. The
color names in the new vehicle ordering guides vary
depending on car line but use the same color code.
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 ultra violet light and provides a durable
high gloss finish.
WET SANDING,BUFFING AND POLISHING
Minor acid etching, orange peel or smudging in clear
coat can be reduced with light wet sanding, hand
buffing and polishing. If the finish has been wet sanded
in the past, it can not be repeated. Wet sanding
operation should be performed by a trained automotive
painter.
CAUTION: Do not remove clear coat finish, if
equipped. Base coat paint must retain clear coat to
shine.
PAINTED SURFACE TOUCH-UP
When a painted metal surface has been scratched or
chipped, it should be touched-up as soon as possible to avoid corrosion. For best results, use Mopar
tScratch
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 Mopar tTar/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 surface
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 (600 grit) wet sanded and polished 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.

HEATER AND A/C PERFORMANCE TESTS
HEATER OUTPUT TEST
PRE-DIAGNOSTIC PREPARATIONS
Review Safety Precautions and Warnings before
performing the following procedures. Check the radiator coolant level, drive belt tension,
and engine vacuum line connections. Also check ra-
diator air flow and radiator fan operation. Start en-
gine and allow to warm up to normal operating
temperature.
WARNING: DO NOT REMOVE RADIATOR CAP
WHEN ENGINE IS HOT, PERSONAL INJURY CAN
RESULT.
If vehicle has been run recently, wait 15 minutes
before removing cap. Place a rag over the cap and
turn it to the first safety stop. Allow pressure to es-
cape through the overflow tube. When the system
stabilizes, remove the cap completely.
MAXIMUM HEATER OUTPUT: TEST AND ACTION
Engine coolant is provided to the heater system by
two 16 mm (5/8 inch inside diameter) heater hoses.
With engine idling at normal running temperature,
set the control to maximum heat, floor, and high
blower setting. Using a test thermometer, check the
air temperature coming from the floor outlets, refer
to Temperature Reference chart.
If the floor outlet air temperature is low, refer to
Group 7, Cooling System for coolant temperature
specifications. Both heater hoses should be HOT to
the touch. The coolant return hose should be slightly
cooler than the supply hose. If coolant return hose is
much cooler than the supply hose, locate and repair
engine coolant flow obstruction in heater system.
POSSIBLE LOCATIONS OR CAUSE OF OBSTRUCTED
COOLANT FLOW
(a) Pinched or kinked heater hoses.
(b) Improper heater hose routing. (c) Plugged heater hoses or supply and return
ports at cooling system connections, refer to Group
7, Cooling System. (d) Plugged heater core.
If proper coolant flow through heater system is ver-
ified and outlet air temperature is still low, a me-
chanical problem may exist.
POSSIBLE LOCATION OR CAUSE OF INSUFFICIENT HEAT
(a) Obstructed cowl air intake.
(b) Obstructed heater system outlets.
(c) Blend-air door not functioning properly.
TEMPERATURE CONTROL If temperature cannot be adjusted with the TEMP
lever on the control panel, or TEMP lever is difficult
to move, the following could require service: (a) Blend-air door binding.
(b) Control cables miss-routed, pinched, kinked,
or disconnected. (c) Improper engine coolant temperature.A/C PERFORMANCE TEST
The air conditioning system is designed to remove
heat and humidity from the air entering the passen-
ger compartment. The evaporator, located in the
heater A/C unit behind the instrument panel, is
cooled to temperatures near the freezing point. As
warm damp air passes over the fins in the evapora-
tor, moisture in the air condenses to water, dehumid-
ifying the air. Condensation on the evaporator fins
reduces the evaporators ability to absorb heat. Dur-
ing periods of high heat and humidity an A/C system
will be less effective than during periods of high heat
and low humidity. With the instrument control set to
RECIRC, only air from the passenger compartment
passes through the evaporator. As the passenger
compartment air dehumidifies, A/C performance lev-
els rise.
PERFORMANCE TEST PROCEDURE
Review Safety Precautions and Warnings before
proceeding with this procedure. Air temperature in
test room and on vehicle must be 70ÉF (21ÉC) mini-
mum for this test. (1) Connect a tachometer and manifold gauge set.
(2) Set control to A/C, RECIRC, PANEL, or MAX
A/C, temperature lever on full cool and blower on
high. (3) Start engine and hold at 1000 rpm with A/C
clutch engaged. (4) Engine should be warmed up with doors and
windows closed.

SIGHT GLASS REFRIGERANT LEVEL INSPECTION
The filter-drier is equipped with a sight glass (Fig.
1) that is used as a refrigerant level indicator only.
This sight glass is not to be used for A/C perfor-
mance testing. To check the refrigerant level re-
move the vehicle jack. Then clean the sight glass,
start and warm up engine, and hold rpm slightly
above idle (1100 rpm). Place the air conditioning con-
trol on A/C, RECIRC and high blower. The work
area should be at least 21ÉC (70ÉF). If a Fixed Dis-
placement type compressor does not engage, the re-
frigerant level is probably too low for the Low
Pressure Cut-Off switch to detect. Or, with a Vari-
able Displacement compressor, for the Differential
Pressure Cut-off to detect. If compressor clutch does
not engage, test the refrigerant system for leaks. If
compressor clutch engages, allow approximately one
minute for refrigerant to stabilize. View refrigerant
through sight glass. The suction line should be cold
to the touch and the sight glass should be clear.
If foam or bubbles are visible in sight glass, the re- frigerant level is probably low. Occasional foam or
bubbles are normal when the work area temperature
is above 43ÉC (110ÉF) or below 21ÉC (70ÉF). If suction
line is cold and occasional bubbles are visible in the
sight glass, block the condenser air flow. This will in-
crease the compressor discharge pressure. Do not al-
low engine to over heat. Bubbles should dissipate.
If not, the refrigerant level is low.
CAUTION: Do not allow engine to over heat while
blocking the condenser air flow.
WARNING: R-12 REFRIGERANT IS DETRIMENTAL
TO THE ENVIRONMENT WHEN RELEASED TO THE
ATMOSPHERE. DO NOT ADD R-12 REFRIGERANT
TO A SYSTEM THAT HAS A KNOWN LEAK.
The refrigerant system will not be low on (R-12)
unless there is a leak. Find and repair the leak be-
fore charging.
R-12 REFRIGERANT EQUIPMENT
WARNING: EYE PROTECTION MUST BE USED
WHEN SERVICING AN AIR CONDITIONING REFRIG-
ERANT SYSTEM. TURN OFF (ROTATE CLOCKWISE)
ALL VALVES ON THE EQUIPMENT BEING USED
BEFORE PROCEEDING WITH THIS OPERATION.
PERSONNEL INJURY CAN RESULT.
When servicing an air conditioning system, an A/C
charging station is recommended (Fig. 2). An (R-12)
refrigerant recovery/recycling device (Fig. 3) should
also be used. This device should meet SAE standards.
Contact an automotive service equipment supplier
for refrigerant recycling/recovering equipment. Refer
to the operating instructions provided with the
equipment for proper operation. A manifold gauge set (Fig. 4) must also be used in
conjunction with the charging and/or recovery/recy-
cling device. The service hoses on the gauge set be-
ing used should have manual (turn wheel) or
automatic back flow valves at the service port con-
nector ends. This will prevent refrigerant from being
release into the atmosphere.
