WINDOW DEFOGGER SYSTEM SYSTEM DESCRIPTION


  1. GENERAL


    1. 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.

      Note

      If the auxiliary battery voltage is low, the window defogger system may not operate due to operation of auxiliary battery load control, check the Data List item "Battery Control Count (Body ECU)".
