Repair Procedure
Caution: To avoid personal injury:
| • | Do not allow the repair material to come in contact with skin
or eyes and avoid breathing vapors. |
| • | Do not use near sparks or open flame. |
- Disconnect the electrical connector.
- Inspect the rear window grid lines.
- Ensure that the rear window is at room temperature.
- Inspect the grid line area that you will repair. Verify that the
area is dry and free from contaminates.
- Dampen a cloth with isopropyl alcohol. Use the damp cloth in order
to wipe the grid line area clean.
Installation Procedure
Tools Required
| • | Heat gun - capable of 260 °C (500 °F) |
| • | Rear Window Defogger Repair Kit GM P/N 12346001 or equivalent |
Important:
| • | Ensure that the grid line repair material is not beyond the expiration
date. |
| • | Repair decal or tape must be used in order to control the width
of the repair area. |
| • | If the repair decal is used, verify that the die-cut metering
slot is the same width as the grid line. |
| • | Thoroughly stir the grid line repair material until a uniform
color appears. |
| • | Verify that there are no air bubbles in the grid line repair material
in the repair area. |
- Use a grease pencil in order to mark the grid line break (2)
on the outside of the rear window with a grease pencil.
- Apply the grid line repair (2)
decal or 2 strips of the tape above and below the repair area.
- Use the brush (3) in order to spread the grid line repair
material (1). Ensure that the repair material covers all of the areas
of the cut out.
Notice: The grid line repair material must be cured with heat. To avoid heat
damage to the interior trim, protect the trim near the repair area where heat
is to be applied.
- Without disturbing the grid line repair material, carefully remove the
decal or tape (2).
Important: If you do not use a heat gun, allow at least 24 hours at an ambient
temperature of 21°-32°C (70°-90°F) for complete
curing of the repair materials. Do NOT physically disturb the repair area
until after that time.
The grid line will be electrically operative immediately after the repair.
- Use a heat gun in order to repair the grid line:
| • | Hold the heat gun nozzle 25 mm (1 in) from the surface. |
| • | Heat the repair area for 2-3 minutes. |
- Connect the electrical connector.
- Test the grid line operation in order to verify the grid line
repair.
