Heated Glass Element: Description and Operation
Voltage is applied at all times through fuse 10 to the rear defogger relay contact. With the ignition in ON or START, voltage is applied through fuse 2 to
the rear defogger switch.
With the rear defogger switch in ON, voltage is applied to the rear defogger relay coil and the rear defogger indicator light. The rear defogger indicator
lights up and the rear defogger relay contact closes. Battery voltage is applied to the rear defogger on the surface of the rear window and the rear
defogger heats the rear window to remove any fog from the glass.
