GENERAL INFORMATION
The electrically-heated rear window defogger is an
available option on XJ (Cherokee), and YJ (Wrangler)
models equipped with the hardtop roof option. Fol-
lowing are general descriptions of the major compo-
nents in the rear window defogger system. Refer to
Group 8W - Wiring Diagrams for complete circuit de-
scriptions and diagrams.
REAR WINDOW GLASS GRID
The heated rear window glass has two electrically-
conductive vertical bus bars and a series of horizon-
tal grid lines made of a silver-ceramic material,
which is baked on and bonded to the inside surface of
the glass. The grid lines and bus bars comprise a
parallel electrical circuit.
When the rear window defogger switch is placed in
the ON position, current is directed to the rear win-
dow grid lines through the bus bars. The grid lines
heat the rear window to clear the surface of fog or
snow. Circuit protection for the heated grid circuit is
provided by fuse 18 (XJ) or fuse 6 (YJ) in the fuse-
block module.
The grid lines and bus bars are highly resistant to
abrasion. However, it is possible for an open to occur
in an individual grid line resulting in no current flow
through the line. The grid lines can be damaged or
scraped off with sharp instruments. Care should be
taken in cleaning the glass or removing foreign ma-
terials, decals or stickers. Normal glass cleaning sol-
vents or hot water used with rags or toweling is
recommended.A repair kit is available to repair the grid lines and
bus bars, or to reinstall the heated glass pigtail
wires.
DEFOGGER SWITCH
The rear window defogger switch is mounted in the
instrument panel left of the steering column for XJ,
or right of the steering column for YJ. The switch cir-
cuit is protected by fuse 8 (XJ) or fuse 9 (YJ) in the
fuseblock module. Actuating the switch energizes the
relay and electronic timer. A light-emitting diode
(LED) in the switch (XJ), or a indicator lamp in the
switch (YJ), illuminates to indicate when the system
is turned on. The defogger switch can not be re-
paired. If faulty, the switch must be replaced.
DEFOGGER RELAY/TIMER
The defogger relay/timer is located in the relay cen-
ter on XJ models, or taped to the instrument panel
wiring harness behind the parking brake pedal in the
left cowl side area on YJ models. When the rear de-
fogger switch is actuated, the rear defogger relay is
energized. This causes current to flow through the
grid circuit for approximately 10 minutes, or until
the rear window defogger switch or ignition switch
are turned off.
DIAGNOSIS
SYSTEM TESTS
Electrically-heated rear window defogger operation
can be confirmed in the following manner:
(1) Turn the ignition switch to the ON position.
(2) Turn rear window defogger control switch ON.
(3) Monitor vehicle voltmeter. With the control
switch ON, a distinct needle deflection should be
noted.(4) The rear window defogger operation can be
checked by feeling the glass. A distinct difference in
temperature between the grid lines and adjacent
clear glass can be detected within 3 to 4 minutes of
operation.
(5) Using a DC voltmeter, contact terminal A (Fig.
1) (passenger side) with the negative lead, and termi-

(3) Retain the tape stripe/decal firmly against flat
surface and separate the carrier from tape stripe/de-
cal.
(4) Use a sponge and apply solution to the tape
stripe/decal adhesive and to panel surface.
(5) Position the adhesive side of tape stripe/decal
on the panel with the bottom aligned with the char-
acter line.
²Align the end of the replacement tape stripe/decal
with the end of existing tape stripe/decal.
²Correctly align the index darts and index notches.
(6) If a complete replacement tape stripe/decal is
not being installed:
²Position the replacement tape stripe/decal section
at the center of the repair area.
²Align it with the existing tape stripe/decal.
²Allow at least 12 mm (1/2 in) of the tape stripe/de-
cal section to overlap the tape stripe/decal edges.
(7) Apply the wetting solution to the outer side of
the tape stripe/decal.
CAUTION: Avoid unnecessary pulling and stretch-
ing at the ends.
(8) Slide a squeegee from the center to the ends of
the tape stripe/decal. Use firm strokes to remove all
of the air bubbles.
(9) If a wrinkle is trapped in the tape stripe/decal
stop immediately. Lift the wrinkled area and re-align
it with the character line to remove the wrinkle.Do
not lift the tape stripe/decal if only a few air
bubbles exist.
(10) Where applicable, allow 12 mm (1/2 in) extra
tape stripe/decal to extend beyond edges.
(11) Fold the excess tape onto the inside flange and
adhere it with finger pressure.
(12) Inspect the tape stripe/decal installation with
the reflected light to find any damage.
(13) Remove all the air and moisture bubbles from
the tape stripe/decal with a needle or pin.
(14) Install any removed components and clean the
vehicle as necessary.
