GENERAL
The rear window defogger wire is attached to the inside of the rear window and defogs the window surface quickly when the rear window defogger switch is pressed. The indicator light on the switch illuminates while the system is operating. This system automatically turns off after approximately 15 minutes.
The rear window defogger system is linked with the mirror defogger.
If the auxiliary battery voltage becomes low, window defogger system operation is cancelled to prioritize supplying power to the power steering system.
