Heated Glass Element: Service and Repair
Window Grid Wire Repair
WINDOW GRID WIRE REPAIR
NOTE:
-
If the first layer of the heated rear window grid (brown) is damaged or missing, it is necessary to apply touch up paint on the glass prior to
applying the silver rear window defroster repair.
-
The grid line material is not embedded into the glass but is baked to the glass surface and consequently can be scraped off. Inoperative lines may
appear to the eye to be undamaged due to residue remaining on the glass and will require diagnosis with a voltmeter or 12V test lamp.
-
An undamaged grid line will have small ridges that project above the surface of the glass and can easily be felt when running a fingernail across
them. Grid lines that have been "razor bladed" will feel smooth when a fingernail is dragged across the affected area. There may be some residue
left on the glass that appears to be grid material but a check with a voltmeter or 12V test lamp will confirm an open circuit.
-
If the brown color under the grid line is damaged or missing (this is very rare), it will be necessary to apply lacquer touch up paint for color match.
This paint must meet specification and should be applied to the glass prior to applying the rear window defroster repair compound.
-
The interior side of the grid lines are not painted, but due to the silver tarnishing will tend to change the grid to a gold or brown color. The repair
area will be bright silver and will also tarnish over time to match the rest of the grid.
1. Bring the vehicle up to room temperature of at least 16°C (60°F) or above.
2. 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.
Clean the entire grid line repair area with window cleaner and 0000 steel wool to remove all dirt, wax, grease, oil or other foreign material.
3. Mark the location of the grid break on the exterior of the rear window glass.
4. Using a polypropylene film fine line tape, mask the area directly above and below the grid break extending the tape 26 mm (1.02 in) beyond the
concern area in both directions. The break area should be at the center of the mask.
