The repair of the grid lines or the terminal is possible using the Mopar (R) Repair Package or equivalent.




1. Mask repair area so conductive epoxy can be extended onto the line or the bus bar.
2. Follow instructions in repair kit for preparing damaged area.
3. Remove package separator clamp and mix plastic conductive epoxy thoroughly. Fold in half and cut center corner to dispense epoxy.
4. For grid line, mark off area to be repaired with masking tape or a template.
5. Apply conductive epoxy through slit in masking tape. Overlap both ends of the break by 19 mm (3/4 inch).
6. For a terminal or pigtail replacement, mask adjacent areas so epoxy can be extended onto line as well as bus bar. Apply a thin layer of epoxy to area where terminal was fastened and to adjacent line.
7. Apply a thin layer of conductive epoxy on terminal and place terminal on desired location. To prevent terminal from moving while the epoxy is curing, it must be wedged or clamped.
8. Carefully remove masking tape from grid line.

CAUTION: Do not allow the glass surface to exceed 204 °C (400 °F), glass may fracture.

9. Allow epoxy to cure 24 hours at room temperature or use heat gun with a 260° to 371 °C (500° to 700 °F) range for 15 minutes. Hold gun approximately 254 mm (10 inches) from repaired area.
10. After conductive epoxy is properly cured remove wedge from terminal and check out operation of rear window defogger. Do not attach connectors until curing is complete.

Rear Window Defogger Grid Lines
The rear window defogger grid lines are serviced with the rear window glass. If a grid line repair does not fix the grid line and allow it to function properly replacement of the liftgate glass is necessary. Refer to Body removal and Installation, Rear Window.
