DIAGNOSIS AND TESTING - REAR WINDOW
DEFOGGER GRID
For circuit descriptions and diagrams, refer to Rear
Window Defogger in Wiring Diagrams. To detect
breaks in the grid lines, the following procedure is
required:
(1) Turn the ignition switch to the On position. Set
the defogger switch in the On position. The indicator
lamp should light. If OK, go to Step 2. If not OK,
(Refer to 8 - ELECTRICAL/HEATED GLASS/REAR
WINDOW DEFOGGER SWITCH - DIAGNOSIS AND
TESTING).
(2) Using a 12-volt DC voltmeter, contact the ver-
tical bus bar on the right side of the vehicle with the
negative lead. With the positive lead, contact the ver-
tical bus bar on the left side of the vehicle. The volt-
meter should read battery voltage. If OK, go to Step
3. If not OK, repair the open circuit to the defogger
relay as required.
(3) With the negative lead of the voltmeter, contact
a good body ground point. The voltage reading should
not change. If OK, go to Step 4. If not OK, repair the
circuit to ground as required.
(4) Connect the negative lead of the voltmeter to
the right side bus bar and touch each grid line at
midpoint C with the positive lead. A reading of
approximately six volts indicates a line is good. A
reading of zero volts indicates a break in the grid
line between midpoint C and the left side bus bar. A
reading of ten to fourteen volts indicates a break
between midpoint C and the right side bus bar. Move
the positive lead on the grid line towards the break
and the voltage reading will change as soon as the
break is crossed.
STANDARD PROCEDURE - REAR WINDOW
DEFOGGER GRID REPAIR
Repair of the rear glass heating grid lines, bus
bars, terminals or pigtail wires can be accomplished
using a Mopar Rear Window Defogger Repair Kit
(Part Number 4267922) or equivalent.
WARNING: MATERIALS CONTAINED IN THE REPAIR
KIT MAY CAUSE SKIN OR EYE IRRITATION. THE
KIT CONTAINS EPOXY RESIN AND AMINE TYPE
HARDENER,
WHICH ARE HARMFUL IF SWAL-
LOWED. AVOID CONTACT WITH THE SKIN AND
EYES. FOR SKIN CONTACT, WASH THE AFFECTED
AREAS WITH SOAP AND WATER. FOR CONTACT
WITH THE EYES, FLUSH WITH PLENTY OF WATER.
DO NOT TAKE INTERNALLY. IF TAKEN INTER-
NALLY, INDUCE VOMITING AND CALL A PHYSICIAN
IMMEDIATELY. USE WITH ADEQUATE VENTILA-
TION. DO NOT USE NEAR FIRE OR FLAME. CON-
TAINS FLAMMABLE SOLVENTS. KEEP OUT OF THE
REACH OF CHILDREN.
(1) Follow the instructions in the repair kit for
preparing the damaged area.
(2) Remove the package separator clamp and mix
the two conductive epoxy components thoroughly
within the packaging. Fold the package in half and
cut the center corner to dispense the epoxy.
(3) For grid line repairs, mask the area to be
repaired with masking tape or a template (Fig. 2).
(4) Apply the epoxy through the slit in the mask-
ing tape or template. Overlap both ends of the break
by at least 19 millimeters (0.75 inch).
(5) For a terminal or pigtail wire replacement,
mask the adjacent areas so the epoxy can be
extended onto the adjacent grid line as well as the
bus bar. Apply a thin layer of epoxy to the area
where the terminal or pigtail wire was fastened and
onto the adjacent grid line.
(6) Apply a thin layer of conductive epoxy to the
terminal or bare wire end of the pigtail and place it
in the proper location on the bus bar. To prevent the
terminal or pigtail wire from moving while the epoxy
is curing, it must be wedged or clamped.
(7) Carefully remove the masking tape or tem-
plate.
CAUTION: Do not allow the glass surface to exceed
204° C (400° F) or the glass may fracture.
(8) Allow the epoxy to cure 24 hours at room tem-
perature, or use a heat gun with a 260° to 371° C
(500° to 700° F) range for fifteen minutes. Hold the
heat gun approximately 25.4 centimeters (10 inches)
from the repair.
(9) After the conductive epoxy is properly cured,
remove the wedge or clamp from the terminal or pig-
tail wire. Do not attach the wire harness connectors
until the curing process is complete.
