on the glass that appears to be grid material but a check with a voltmeter or 12V test lamp, as explained in this article, will confirm an open circuit.
GRID LINE REPAIR PROCEDURE
NOTE
^
Long gaps are almost always due to damage and are not warrantable, however they can be repaired. The longer the gap the more important it is to
apply a minimum six (6) coats of conductive repair material with the five (5) minute dry time between each coat. Applying less coats or not
allowing dry time between coats will produce repaired resistance that is greater than ohm resistance, resulting in poor defrost performance and
excessive localized heating.
^
Repaired long gaps are generally not visually pleasing unless extreme care is taken when taping affected grid line areas.
^
If the brown color under the grid line is damaged or missing (this is very rare), it will be necessary to apply brown acrylic lacquer touch-up paint
for color match. This paint must meet specification ESR-M2P100-C and should be applied to the glass prior to applying the rear window
defroster repair compound.
Service inoperative grid lines on rear window glass using Rear Window Defroster Repair 0000-88-5067 or equivalent as follows:
Surface Preparation
1.
Bring vehicle inside and warm it to 60 F (16 C) or above.
2.
Clean the entire grid line service area with glass cleaner to remove all dirt, wax, grease, oil or other foreign matter. It is important that the repair
area be clean and dry.
3.
Lightly buff damaged area with "FINE" steel wool.
NOTE:
Do not use scrapers, sharp instruments, or abrasive window cleaners on the interior surface of the rear window glass as this may cause damage
to the grid lines.
Mixing
^
The bottle of Rear Window Defroster Repair compound and touch-up paint (if needed) must be at room temperature.
^
Shake the bottle for at least one (1) minute for thorough mixing.
^
Shake frequently during use.
Application
4.
Mark location of open grid on the outside of the back window glass (performed in diagnostics). Place protective covering over the package tray as
necessary.
5.
Using "fine line tape", mask off the area directly above and below open grid line. It is best to extend the tape 26 mm (1") beyond the concern area
in both directions.
NOTE:
^
The open grid line should be at the center of the mask and tape gap must be no wider than the existing grid line.
^
Other types of tape may be used but end results of the repair may not appear as visually acceptable due to ease of application and tape edge
finish.
