BASE COAT/CLEARCOAT
FINISH
DESCRIPTION
On most vehicles a two-part paint application
(basecoat/clearcoat) is used. Color paint that is
applied to primer is called basecoat. The clearcoat
protects the basecoat from ultraviolet light and pro-
vides a durable high-gloss finish.
CAUTION: Do not use abrasive chemicals or com-
pounds on painted surfaces. Damage to finish can
result.
Do not use harsh alkaline based cleaning solvents
on painted surfaces. Damage to finish or color can
result.
PAINT CODE
DESCRIPTION
Exterior vehicle body colors are identified on the
Body Code plate. (Refer to VEHICLE DATA/VEHI-
CLE INFORMATION/BODY CODE PLATE -
DESCRIPTION). The paint code is also identified on
the Vehicle Safety Certification Label which is
located on the drivers door shut face. The first digit
of the paint code listed on the vehicle indicates the
sequence of application, i.e.: P = primary coat, Q =
secondary coat. The codes listed in the Color Code
Chart are used for manufacturing purposes.
PAINTED TOUCH-UP
DESCRIPTION
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 VEHICLE DATA/VEHICLE INFOR-
MATION/BODY CODE PLATE - DESCRIPTION).
WARNING: USE AN OSHA APPROVED RESPIRATOR
AND SAFETY GLASSES WHEN SPRAYING PAINT
OR SOLVENTS IN A CONFINED AREA. PERSONAL
INJURY CAN RESULT.
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 scratch or chip without run-
ning. 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 clearcoat, the touch up
color can be lightly finesse sanded (1500 grit) and
polished with rubbing compound.
(6) On vehicles with clearcoat, 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.
WARNING: AVOID PROLONGED SKIN CONTACT
WITH PETROLEUM OR ALCOHOL ± BASED CLEAN-
ING SOLVENTS. PERSONAL INJURY CAN RESULT.
FINESSE SANDING/BUFFING &
POLISHING
DESCRIPTION
Minor acid etching, orange peel, or smudging in
clearcoat or single-stage finishes can be reduced with
light finesse sanding, hand buffing, and polishing.If
the finish has been finesse sanded in the past,
it cannot be repeated. Finesse sanding opera-
tion should be performed by a trained automo-
tive paint technician.
CAUTION: Do not remove clearcoat finish, if
equipped. Basecoat paint must retain clearcoat for
durability.

WINDSHIELD
DESCRIPTION
The windshield is attached to the window frame
with urethane adhesive. The urethane adhesive is
applied cold and seals the surface area between the
window opening and the glass. The primer adheres
the urethane adhesive to the windshield.
It is difficult to salvage a windshield during the
removal operation. The windshield is part of the
structural support for the roof. The urethane bonding
used to secure the windshield to the fence is difficult
to cut or clean from any surface. If the moldings are
set in urethane, it would also be unlikely they could
be salvaged. Before removing the windshield, check
the availability of the windshield and moldings from
the parts supplier.
WARNING
WINDSHIELD SAFETY PRECAUTIONS
WARNING: DO NOT OPERATE THE VEHICLE
WITHIN 24 HOURS OF WINDSHIELD INSTALLATION.
IT TAKES AT LEAST 24 HOURS FOR URETHANE
ADHESIVE TO CURE. IF IT IS NOT CURED, THE
WINDSHIELD MAY NOT PERFORM PROPERLY IN
AN ACCIDENT.
URETHANE ADHESIVES ARE APPLIED AS A SYS-
TEM. USE GLASS CLEANER, GLASS PREP SOL-
VENT, GLASS PRIMER, PVC (VINYL) PRIMER AND
PINCH WELD (FENCE) PRIMER PROVIDED BY THE
ADHESIVE MANUFACTURER. IF NOT, STRUCTURAL
INTEGRITY COULD BE COMPROMISED.
DAIMLERCHRYSLER DOES NOT RECOMMEND
GLASS ADHESIVE BY BRAND. TECHNICIANS
SHOULD REVIEW PRODUCT LABELS AND TECHNI-
CAL DATA SHEETS, AND USE ONLY ADHESIVESTHAT THEIR MANUFACTURES WARRANT WILL
RESTORE A VEHICLE TO THE REQUIREMENTS OF
FMVSS 212. TECHNICIANS SHOULD ALSO INSURE
THAT PRIMERS AND CLEANERS ARE COMPATIBLE
WITH THE PARTICULAR ADHESIVE USED.
BE SURE TO REFER TO THE URETHANE MANU-
FACTURER'S DIRECTIONS FOR CURING TIME
SPECIFICATIONS, AND DO NOT USE ADHESIVE
AFTER ITS EXPIRATION DATE.
VAPORS THAT ARE EMITTED FROM THE URE-
THANE ADHESIVE OR PRIMER COULD CAUSE
PERSONAL INJURY. USE THEM IN A WELL-VENTI-
LATED AREA.
SKIN CONTACT WITH URETHANE ADHESIVE
SHOULD BE AVOIDED. PERSONAL INJURY MAY
RESULT.
ALWAYS WEAR EYE AND HAND PROTECTION
WHEN WORKING WITH GLASS.
CAUTION: Protect all painted and trimmed surfaces
from coming in contact with urethane or primers.
Be careful not to damage painted surfaces when
removing moldings or cutting urethane around
windshield.
REMOVAL
WINDSHIELD REMOVAL ± EXTERIOR METHOD

SUNROOF
DESCRIPTION
WARNING: Keep fingers and other body parts out
of sunroof opening at all times.
The sun roof features consists of: (Fig. 1)
²Sun roof glass
²Sun roof sun shade
The sunroof power sliding glass panel and sun-
shade can be positioned anywhere along its travel,
rearward of glass panel front edge.
The sunroof is electrically operated from a switch
located in the overhead console. To operate the sun-
roof the ignition switch must be in the Accessory or
On/Run position. Both switchs are a rocker style
design that open or close the sunroof. When pressing
and releasing the open button once, the sunroof will
express open to the comfort stop and the wind deflec-
tor will raise. If the button is pressed a second time,
the sunroof will continue to open to full travel unless
the button is released, at which time it will stop in
that position. Pressing and holding the close button
will close the sunroof. If the close button is released
before the glass fully closes, the sunroof will stop in
that position. The vent switch operates in a similar
manor. The sunroof will also operate for up to fifteen
minutes after the ignition key is turned off for cus-
tomer comfort and convenance while parking.
DIAGNOSIS AND TESTING - SUNROOF
Refer to Sunroof Diagnostic Chart for possible
causes. Before beginning sunroof diagnostics verify
that all other power accessories are in proper operat-
ing condition. If not, a common electrical problem
may exist. Refer to Wiring Diagrams, in this publica-
tion for circuit, splice and component descriptions.
Check the condition of the circuit protection (20 amp
circuit breaker in the Junction Block). Inspect all
wiring connector pins for proper engagement and
continuity. Check for battery voltage at the power
sunroof controller, refer to Wiring Diagrams, for cir-
cuit information. If battery voltage of more than 10
volts is detected at the controller, proceed with the
following tests (the controller will not operate at less
than 10 volts).
Before beginning diagnosis for wind noise or water
leaks, verify that the problem was not caused by
releasing the control switch before the sunroof was
fully closed. The sunroof module has a water-man-
agement system. If however, the sunroof glass is in a
partial closed position, high pressure water may be
forced beyond the water management system bound-
aries and onto the headlining.

diagnose the A/C system control and distribution sys-
tems. Refer to the appropriate diagnostic informa-
tion.
MANUAL TEMPERATURE CONTROL
The front blower speed and rear blower speed (if
equipped with rear HVAC) must be set to High and
the evaporator temperature sensor must be greater
than 55É F or the test will fail immediately. The test
is activated by depressing the A/C and PWR buttons
simultaneously and holding them depressed for no
less than five seconds. The PWR and A/C LEDs will
blink on and off until the test is complete. If the
LEDs stop blinking before two minutes, then the cool
down test has been completed successfully. If the two
minutes expire without the expansion valve temper-
ature reaching 20É F less than the outside air tem-
perature, then the cool down test has been failed and
further A/C system diagnosis is required. If the test
is failed, the LEDs will continue to blink until the
vehicle has been driven for greater than (8 miles).
AUTOMATIC TEMPERATURE CONTROL
The ambient air temperature in the room where
the vehicle will be tested must be a minimum of 21É
C (70ÉF) for this test. The test is activated by
depressing the A/C and PWR buttons simultaneously
and holding them depressed for no less than four sec-
onds. The snowflake icon and the DELAY text in the
ATC display will blink on and off alternately until
the test is complete. If the snowflake icon and the
DELAY text stop blinking before two minutes, then
the cool down test has been completed successfully. If
the two minutes expire without the evaporator tem-
perature reaching 20É F less than the evaporator ini-
tial temperature, then the cool down test has been
failed and further A/C system diagnosis is required.
If the test is failed, the snowflake icon and the
DELAY text will continue to blink across ignition
cycles until the vehicle has been driven for greater
than (8 miles).
DIAGNOSIS AND TESTING - A/C
PERFORMANCE TEST
An air conditioning performance test is the best
way to determine whether the system is performing
up to standard. This test also provides valuable clues
as to the possible cause of trouble with the air con-
ditioning system. The ambient air temperature in the
location where the vehicle will be tested must be a
minimum of 21É C (70ÉF) for this test.
WARNING: REFER TO THE APPLICABLE WARN-
INGS AND CAUTIONS FOR THIS SYSTEM BEFOREPERFORMING THE FOLLOWING OPERATION.
(Refer to 24 - HEATING & AIR CONDITIONING/
PLUMBING - FRONT - WARNING - A/C PLUMBING)
and (Refer to 24 - HEATING & AIR CONDITIONING/
PLUMBING - FRONT - CAUTION - A/C PLUMBING).
NOTE: When connecting the service equipment
coupling to the line fitting, verify that the valve of
the coupling is fully closed. This will reduce the
amount of effort required to make the connection.
(1) Connect a tachometer to monitor the engine
speed.
(2) Remove the caps from the refrigerant system
service ports and attach a manifold gauge set to
monitor the refrigerant system pressures.
(3) Set the heater-air conditioner controls so that
the compressor is engaged, the air within the vehicle
is being recirculated, the output air is directed
through the panel outlets, the temperature control is
in the full cool position, and the blower motor is oper-
ating at its highest speed.
(4) Start the engine and allow the engine to oper-
ate for about five minutes or until it reaches normal
operating temperature. Then hold the engine speed
at 1000 rpm with the compressor clutch engaged. If
the compressor clutch does not engage, proceed with
diagnosis of the compressor clutch coil. (Refer to 24 -
HEATING & AIR CONDITIONING/CONTROLS -
FRONT/COMPRESSOR CLUTCH COIL - DIAGNO-
SIS AND TESTING).
(5) Close all the vehicle windows and doors.
(6) Insert a thermometer in the left center panel
outlet and operate the engine for five minutes.
(7) With the compressor clutch engaged, record the
left center panel outlet discharge air temperature,
the discharge pressure (high side service port), and
the suction pressure (low side service port). The com-
pressor clutch may cycle, depending upon the ambi-
ent temperature and humidity. If the clutch cycles,
use the readings obtained before the clutch disen-
gaged.
(8) Compare the discharge air temperature read-
ing to the Performance Temperature and Pressure
chart. If the temperature reading is high, check the
refrigerant system for leaks and proper refrigerant
charge level. (Refer to 24 - HEATING & AIR CONDI-
TIONING/PLUMBING - FRONT/REFRIGERANT -
DIAGNOSIS AND TESTING - REFRIGERANT SYS-
TEM LEAKS) and (Refer to 24 - HEATING & AIR

graphics will begin to flash when the calibration pro-
cedure has begun.
(3) The calibration procedure should take less than
two minutes to complete for the manual heater-A/C
control, and less than twenty seconds for the ATC
heater-A/C control. When the LEDs or graphics stop
flashing, the calibration procedure is complete.
(4) If the LEDs or graphics continue to flash
beyond the normal three minute (manual) or twenty
second (ATC) calibration time, it indicates that the
heater-A/C control has detected a failure and a Diag-
nostic Trouble Code (DTC) has been set. Use a
DRBIIItscan tool to perform further diagnosis. Refer
to the appropriate diagnostic information. The LEDs
or graphics will continue to flash even after the igni-
tion switch is cycled Off and On, until a successful
calibration is completed or until the vehicle has been
driven about 13 kilometers (8 miles).
