Grid Wire Repair

Heat Gun:

SPECIAL SERVICE TOOL(s)

NOTE: Any breaks longer than 25.4 mm (1 in) in one grid cannot be repaired. The back window glass must be replaced. Breaks equal to or shorter than 25.4 mm (1 in) in the heated back window grid wire can be successfully repaired by using the following procedure:

1. Obtain a grid wire repair repair kit meeting Ford specification ESB-M4J58-A.
2. The vehicle should be brought inside and allowed to reach 16°C (60°F) or above.
3. Clean the repair area with denatured alcohol.







4. Place the grid line mask over the break, aligning the cutout slots on either side of the repair area.
5. Apply the epoxy to the repair area.
6. Remove the mask without disturbing the epoxy.
7. Use the heat gun to heat the repair area for one to two minutes at a distance of about 25-50 mm (1-2 in). This procedure should heat the repair area to approximately 149°C (300°F).
8. The heated back window may be energized immediately after the repair. Optimum hardness and adhesion will occur after 24 hours. Do not disturb the repaired area until that time.
