Antenna Grid Wire Repair

MATERIAL SPECIFICATIONS

Item Specification
Rear Window Defroster Repair D8AZ-19562-AA or equivalent WSB-M4J58-B
NOTE: Any breaks longer than 25.4 mm (1 inch) in one grid cannot be repaired. The right quarter window glass must be replaced. Breaks equal to or shorter than 25.4 mm (1 inch) in the antenna grid wire can be successfully repaired by using the following procedure.
NOTE: The grid line is very close to the interior trim/headliner. It is recommended to remove the trim (or drop the headliner) in the vicinity of the repair area to allow full access to the grid line and to prevent any damage to the trim/headliner while following the repair procedure.
  1. Bring the vehicle up to room temperature of at least 16°C (60°F) or above.
  2. Clean the entire grid line repair area with a non-alcohol based window cleaner and 0000 steel wool.
  3. Mark the location of the grid break on the exterior of the rear window glass.
