Window Defogger Grid: Description

The heated rear window defogger uses a heating grid baked to the inside of the rear window. Window heat is controlled by a control switch and relay-timer. When the defogger is operating, an indicator lamp will light to show the system is on. Current feed to the defogger is through a circuit breaker (30 amp. on most models), and power to the control switch is through a fuse in the fuse panel.
