WINDOW DEFOGGER SYSTEM SYSTEM DESCRIPTION


  1. 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.

    Tech Tips

    If both of the following conditions are met after approximately 15 minutes from when the rear window defogger system was activated, the rear window defogger system continues to operate up to approximately 45 minutes. If the following conditions are not met, the rear window defogger system stops operating immediately.


    • The outside temperature is -3°C (27°F) or lower.
