Heated Glass Element: Service and Repair

Defogger Wire Repair

NOTE: To make an effective repair, the broken section must be no longer than one 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 silver conductive paint extending about 1/8" on both sides of the break. Allow 30 minutes to dry.
4. Recheck voltage on the repaired wire.
5. Apply a second coat of paint in the same way. Let it dry 3 hours before removing the tape.
