1. WINDOW DEFOGGER SYSTEM DESCRIPTION
The thin heater wires of the defogger system are attached to the rear window and defog the rear window surface quickly. The system only operates when the back door power window is closed. The indicator light illuminates while the system is operating. The system automatically turns off when the back door power window is opened, or approximately 15 minutes after operation starts. For vehicles with an air conditioning system, there is a timer extension function which can operate the window defogger system for up to an additional 255 minutes.
