Heated Glass Element: Description and Operation

- When the ignition switch is at the ON position and the defogger switch is set to the ON (automatic return switch) position, current flows from the defogger timer to the coil side of the defogger relay for a period of 9 to 11 minutes.
- When the defogger relay contact closes to turn the defogger relay on and the defogger has operated for 9 to 11 seconds, the indicator light of the defogger switch illuminates at the same time to inform the driver that the defogger is operating.

NOTE:
- After the defogger has operated for 9 to 11 minutes, it will automatically stop. Also, if the defogger switch is pressed again while the defogger is operating or if there is no generator current (terminal U' drops to 3.5 V or below), the defogger will stop operating.
- When the lighting switch is set to the TAIL or HEAD position, the tail light relay contact closes to turn the tail light relay on, and the defogger switch illumination light will illuminate.
