DOOR GLASS
REMOVAL
(1) Remove the rear door glass run channel. (Refer
to 23 - BODY/DOORS - REAR/GLASS RUN CHAN-
NEL - REMOVAL)
INSTALLATION
(1) Install the rear door glass run channel. (Refer
to 23 - BODY/DOORS - REAR/GLASS RUN CHAN-
NEL - INSTALLATION)
QUARTER WINDOW
REMOVAL
(1) Remove the headliner as necessary to gain
access to the glass seal from the inside. (Refer to 23 -
BODY/INTERIOR/HEADLINER - REMOVAL)
(2) Cut urethane bonding from around quarter
window glass using a suitable sharp cold knife. A
pneumatic cutting device can be used if available.
(3) Separate glass from vehicle.
INSTALLATION
CAUTION: Open a window before installing glass.
This will avoid pressurizing the passenger compart-
ment. If a door or swing gate flip-up glass is
slammed before urethane is cured, water leaks can
result.
The window opening fence should be cleaned of old
urethane bonding material.
(1) Install the headliner as necessary. (Refer to 23
- BODY/INTERIOR/HEADLINER - INSTALLATION)
(2) Clean inside of glass with Mopar Glass Cleaner
and lint-free cloth.
(3) Apply PVC (vinyl) primer 25 mm (1 in.) wide
around edge of glass. Wipe with clean/dry lint-free
cloth.
(4) Apply fence primer around edge of fence. Allow
at least eighteen minutes drying time.
(5) Apply a 10 mm (0.4 in.) bead of urethane
around window vinyl border location.
(6)

WINDSHIELD
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.
²URETHANE ADHESIVES ARE APPLIED AS A
SYSTEM. USE GLASS CLEANER, GLASS PREP
SOLVENT, GLASS PRIMER, PVC (VINYL) PRIMER
AND PINCH WELD (FENCE) PRIMER PROVIDED BY
THE ADHESIVE MANUFACTURER. IF NOT, STRUC-
TURAL INTEGRITY COULD BE COMPROMISED.
²DAIMLERCHRYSLER DOES NOT RECOMMEND
GLASS ADHESIVE BY BRAND. TECHNICIANS
SHOULD REVIEW PRODUCT LABELS AND TECHNI-
CAL DATA SHEETS, AND USE ONLY ADHESIVES
THAT 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.
²BE SURE TO REFER TO THE URETHANE MAN-
UFACTURER'S DIRECTIONS FOR CURING TIME
SPECIFICATIONS, AND DO NOT USE ADHESIVE
AFTER ITS EXPIRATION DATE.
²VAPORS THAT ARE EMITTED FROM THE URE-
THANE ADHESIVE OR PRIMER COULD CAUSE
PERSONAL INJURY. USE THEM IN A WELL-VENTI-
LATED AREA.
²SKIN CONTACT WITH URETHANE ADHESIVE
SHOULD BE AVOIDED. PERSONAL INJURY MAY
RESULT.
²ALWAYS 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
(1) Remove inside rear view mirror. (Refer to 23 -
BODY/INTERIOR/REAR VIEW MIRROR -
REMOVAL)
(2) Remove cowl cover. (Refer to 23 - BODY/EXTE-
RIOR/COWL GRILLE - REMOVAL)(3) Remove screws attaching windshield side mold-
ing to A-pillar.
(4) Remove upper windshield molding.
(5) Cut urethane bonding from around windshield
using a suitable sharp cold knife. A pneumatic cut-
ting device can be used if available.
(6) Separate windshield from vehicle.
INSTALLATION
WARNING: REVIEW ALL WARNINGS AND CAU-
TIONS IN THIS GROUP BEFORE PRECEDING WITH
INSTALLATION.
CAUTION: Open a window before installing wind-
shield. This will avoid pressurizing the passenger
compartment. If a door or swing gate flip-up glass
is slammed before urethane is cured, water leaks
can result.
The windshield fence should be cleaned of old ure-
thane bonding material. Support spacers should be
cleaned and properly installed on weld studs or
repair screws at bottom of windshield opening.
(1) Place replacement windshield into windshield
opening. Position glass in the center of the opening
against the support spacers. Mark the glass at the
support spacers with a grease pencil or masking tape
and ink pen to use as a reference for installation.
Remove replacement windshield from windshield
opening.
(2) Position the windshield inside up on a suitable
work surface with two padded, wood 10 cm by 10 cm
by 50 cm (4 in. by 4 in. by 20 in.) blocks, placed par-
allel 75 cm (2.5 ft.) apart.
(3) Clean inside of windshield with Mopar Glass
Cleaner and lint-free cloth.
(4) Apply clear glass primer 25 mm (1 in.) wide
around edge of windshield. Wipe with clean/dry lint-
free cloth.
(5) Apply black-out primer 15 mm (.75 in.) wide on
top and sides of windshield and 25 mm (1 in.) on bot-
tom of windshield. Allow at least three minutes dry-
ing time.
(6) Position windshield spacers on lower fence
above support spacers at the edge of the windshield
opening.
(7) Align the dot on the upper molding to the tick
mark in the center of the glass and install upper
molding onto windshield.
(8) Apply a 10 mm (0.4 in.) bead of urethane
around perimeter of windshield along the inside of
the moldings. Apply two beads along the bottom
edge.

2. Faulty fuse. 2. Check the fuses in the Power Distribution
Center and the junction block. Repair the shorted
circuit or component and replace the fuses, if
required.
3. Faulty a/c compressor
clutch coil.3. See A/C Compressor/Diagnosis and Testing -
Compressor Clutch Coil in this group. Test the
compressor clutch coil and replace, if required.

temperatures at center panel
outlet are too high.1. Excessive refrigerant oil in
system.1. See Refrigerant Oil/Standard Procedure -
Refrigerant Oil Level in this group. Recover the
refrigerant from the refrigerant system and
inspect the refrigerant oil content. Restore the
refrigerant oil to the proper level, if required.
2. Blend door inoperative or
sealing improperly.2. See Blend Door in this group. Inspect the
blend door for proper operation and sealing and
correct, if required.
3. Blend door actuator faulty

2. Refrigerant flow through
the accumulator is restricted.2. See Accumulator in this group. Replace the
restricted accumulator, if required.
3. Refrigerant flow through
the evaporator coil is
restricted.3. See A/C Evaporator in this group. Replace the

(5) Connect the test set hose or probe to the open
end of the leaking circuit. The test set gauge should
return to the 27 kPa (8 in. Hg.) setting shortly after
each connection is made. If OK, replace the faulty
disconnected component. If not OK, go to Step 6.
(6)
To locate a leak in a vacuum line, leave one end
of the line plugged and connect the test set hose or
probe to the other end of the line. Run your fingers
slowly along the line while watching the test set gauge.
The vacuum reading will fluctuate when your fingers
contact the source of the leak. To repair the vacuum
line, cut out the leaking section of the line. Then, insert
the loose ends of the line into a suitable length of 3 mil-
limeter (0.125 inch) inside diameter rubber hose.
STANDARD PROCEDURE - DIODE
REPLACEMENT
(1) Disconnect the battery negative cable and iso-
late it.
(2) Locate the diode in the harness, and remove
the protective covering.
(3) Remove the diode from the harness, pay atten-
tion to the current flow direction (Fig. 5).
(4) Remove the insulation from the wires in the
harness. Only remove enough insulation to solder in
the new diode.
(5) Install the new diode in the harness, making
sure current flow is correct. If necessary refer to the
appropriate wiring diagram for current flow.
(6) Solder the connection together using rosin core
type solder only.Do not use acid core solder.
(7) Tape the diode to the harness using electrical
tape making, sure the diode is completely sealed
from the elements.
(8) Re-connect the battery negative cable, and test
affected systems.
