The system uses a applied to the inner surface of the rear glass. When current passes through these lines, they generate heat to clear fog or frost. Operating Voltage: 12V DC. Operating Voltage: 12V DC

The grid is grounded on the opposite side of the window (usually the left or right pillar). 🔍 Troubleshooting & Common Issues If your defogger is not working, check these in order: When you press the defogger button, a signal
