Loyale (3-Door Model)

When rear defogger switch is turned on, rear defogger timer grounds solenoid circuit of rear defogger relay. This allows power supply to defogger grid. Indicator light on instrument cluster comes on when defogger is on. When defogger has been on for about 18 minutes, rear defogger timer removes ground from rear defogger relay solenoid circuit. This interrupts power supply to defogger grid.
