2888999 - E3030 HEATED REAR WINDSCREEN AND DOOR MIRROR DEFROSTING - Description
Description
The rear window heater element, door mirror demister coils and
the windscreen heater element absorb a considerable amount of energy.
They must therefore be turned off once they have been working for
a certain period of time.The engagement of the resistances for defrosting
the rearscreen and the external rear view mirrors is controlled,
in a timed fashion, by the special button, in the switch unit in
the centre of the dashboard; the button, which is dimly lit when
the ignition is switched on, comes on brightly when the heated rear
windscreen is switched on.The defrosting circuit is protected by a
special fuse and controlled by a specific relay located in the junction
box.
