Heated Glass Element: Service and Repair

Rear Window Defogger Wire Repair

NOTE: To make an effective repair, the broken section must be no longer than 1 inch (25 mm).

1. Lightly rub the area around the broken section (A) with fine steel wool, then clean it with isopropyl alcohol.





2. Carefully mask above and below the broken portion of the defogger wire (B) with cellophane tape (C).

3. Mix the silver conductive paint (commercially available) thoroughly. Using a small brush, apply a heavy coat of paint (A) extending about 1/8 " on both sides of the break. Allow 25 minutes to dry.





4. Do the function test Testing and Inspection to confirm that the wire is repaired.

5. Apply a second coat of paint in the same way. Let it dry 3 hours before removing the tape.
