Testing Grid Lines - Repair Procedure

1. Disconnect battery feed rear window defogger system.
2. Inspect rear window defogger grid lines and mark grid line breaks on outside of glass with a grease pencil.
3. Clean grid line area to be repaired. Buff with steel wool and wipe clean using cloth dampened with alcohol. Buff and clean about 6 mm (1/4 in.) beyond each side of break in guide line.

IMPORTANT: Repair decal or tape must be used to control width of repair area. If decal is used, be sure the die-cut metering slot is the same width as the grid line.

4. Install grid line repair decal or two strips of tape positioned above and below repair area.
5. At room temperature, apply grid line repair material to repair area using the applicator provided with kit.
6. Carefully remove the decal or tape.

NOTE: The grid line repair material must be cured with heat. To avoid heat damage to interior trim, protect the trim near the repair area where heat is to be applied.

IMPORTANT: At least 24 hours are required for complete curing of repair materials, the unit should not be physically disturbed until after that time.




7. Apply heat to repair area for one to two minutes holding heat gun nozzle 25-50 mm (1-2 inches) from surface (Distance A). A minimum temperature of 149°C (300°F) is required.
8. Inspect grid line repair area. If repair appears discolored, apply a coating of tincture of iodine to repair area using a pipe cleaner or fine brush. Allow iodine to dry for about 30 seconds and carefully wipe off excess with lint free cloth.
9. Test rear defogger operation to verify grid line repair.
