Repair of the rear glass heating grid lines and bus bars can be accomplished using the Mopar(R) Rear Window Defogger Repair Kit (Part Number 04549275) or equivalent.

  1. Mask the repair area with masking tape or use a template so that the conductive epoxy can be applied neatly. See Fig 1. Extend the epoxy application onto the grid line or the bus bar on each side of the break.
  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. 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).
  5. 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.
  6. Carefully remove the masking tape or template.
    CAUTION: Do not allow the glass surface to exceed 204Β° C (400Β° F) when using a heat gun, or the glass may fracture.
  7. 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 204Β° C (400Β° F).
  8. After the conductive epoxy is properly cured, check the operation of the rear window defogger glass heating grid.
