Heated Glass Element: Service and Repair
Defogger Wire RepairNOTE: To make an effective repair, the broken section must be no longer than 1 inch.
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 transparent tape (C).
3. Thoroughly mix the silver conductive paint (commercially available defogger grid repair material). Using a small brush, apply a heavy coat of the silver conductive paint extending about 1/8" on both sides of the break. Allow 30 minutes to dry.
4. Check for continuity in the repaired wire.
5. Apply a second coat of paint in the same way. Let it dry 3 hours before removing the tape.
