²Power Outlets
The power distribution system also incorporates
various types of circuit control and protection fea-
tures, including:
²Automatic resetting circuit breakers
²Blade-type fuses
²Bus bars
²Cartridge fuses²Circuit splice blocks
²Flashers
²Fusible links
²Standard and Micro-Relays
Following are general descriptions of the major
components in the power distribution system. See the
owner's manual in the vehicle glove box for more
information on the features and use of all of the
power distribution system components. Refer to Wir-
ing Diagrams for complete circuit diagrams.
OPERATION
The power distribution system for this vehicle is
designed to provide safe, reliable, and centralized dis-
tribution points for the electrical current required to
operate all of the standard and optional factory-in-
stalled electrical and electronic powertrain, chassis,
safety, security, comfort and convenience systems. At

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 liftgate 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 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).
(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 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.
