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 sup-
port spacers with a grease pencil or masking tape and
ink pen to use as a reference for installation. Remove
replacement windshield from windshield opening (Fig. 6).
(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 (Fig. 7).

Apply black-out primer 15 mm (.75 in.) wide on
top and sides of windshield and 25 mm (1 in.) on bottom
of windshield. Allow at least three minutes drying time.
(6) Position windshield spacers on lower fence
above support spacers at the edge of the windshield
opening (Fig. 4).
(7)
Apply a 10 mm (0.4 in.) bead of urethane around
perimeter of windshield along the inside of the mold-
ings. Apply two beads along the bottom edge.
(8) Install upper molding onto windshield.
(9) Apply fence primer around the perimeter of the
windshield opening fence. Allow at least 18 minutes
drying time.
(10) With aid of a helper, position windshield over
windshield opening. Align reference marks at bottom
of windshield to support spacers.
(11) Slowly lower windshield glass to windshield
opening fence. Guide top molding into proper position
if necessary. Push windshield inward to fence spacers
at bottom and until top molding is flush to roof line.
(12) Clean excess urethane from exterior with
Mopar Super Clean or equivalent.
(13) Install windshield side moldings.
(14) Install cowl cover and wipers.
(15) Install inside rear view mirror.
(16) After urethane has cured, water test wind-
shield to verify repair.

Pressure Diagnosis
Condition Possible Causes Correction
Rapid compressor clutch
cycling (ten or more cycles
per minute).1. Low refrigerant system
charge.1. See Plumbing/Diagnosis and Testing -
Refrigerant System Leaks in this group. Test the
refrigerant system for leaks. Repair, evacuate and
charge the refrigerant system, if required.
Equal pressures, but the
compressor clutch does not
engage.1. No refrigerant in the
refrigerant system.1. See Plumbing/Diagnosis and Testing -
Refrigerant System Leaks in this group. Test the
refrigerant system for leaks. Repair, evacuate and
charge the refrigerant system, if required.
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.
4. Faulty compressor clutch
relay.4. See A/C Compressor Clutch Relay/Diagnosis
and Testing - Compressor Clutch Relay in this
group. Test the compressor clutch relay and relay
circuits. Repair the circuits or replace the relay, if
required.
6. Faulty a/c high pressure
transducer.6. See A/C High Pressure Transducer/Diagnosis
and Testing in this group. Test the a/c high
pressure transducer and replace, if required.
7. Faulty Fin Probe. 7. Check for open circuit.
8. Faulty Powertrain Control
Module (PCM).8. Refer to the proper Diagnostic Procedures
manual for testing of the PCM. Test the PCM and
replace, if required.

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
