STANDARD PROCEDURE
GRID LINE AND TERMINAL REPAIR
WARNING: Materials contained in the Repair Kit (Part Number 04549275) may cause skin or eye irritation.
The kit contains epoxy resin and amine type hardener, which are harmful if swallowed. 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 internally, induce vomiting and call a physician
immediately. Use with adequate ventilation. Do not use near fire or flame. Contains flammable solvents.
Keep out of the reach of children. Failure to follow the warnings could result in possible personal injury or
death.
Repair of the rear glass heating grid lines, bus bars, terminals or pigtail wires can be accomplished using the Mopar
Rear Window Defogger Repair Kit (Part Number 04549275) or equivalent.
1. Mask the repair area with masking tape (3) so that
the conductive epoxy can be applied neatly. Extend
the epoxy application onto the grid line (2) or the
bus bar on each side of the break (1).
2. Follow the instructions in the repair kit for preparing
the damaged area.
3. 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.
4. For grid line repairs, mask the area to be repaired
with masking tape or use a template.
5. Apply the epoxy through the slit in the masking
tape or template. Overlap both ends of the break
by at least 19 millimeters (0.75 inch).
6. 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.
7. 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.
8. Carefully remove the masking tape or template.
CAUTION: Do not allow the glass surface to exceed 204° C (400° F) when using a heat gun, or the glass
may fracture.
9. Allow the epoxy to cure 24 hours at room temperature, or carefully use a heat gun for fifteen minutes. When
using a heat gun, hold it approximately 25.4 centimeters (10 inches) from the repair and do not allow the glass
surface to exceed 204° C (400° F).
10. After the conductive epoxy is properly cured, remove the wedge or clamp from the terminal or pigtail wire.
11. Connect the wire harness leads to the grid terminals or pigtail wires and verify EBL operation.
