HEATER - Description

Description

The vehicle climate control system involves a duct/distributor unit with a heater, controlled via three knobs in the dashboard:

• the left knob mechanically controls the mixture flap between hot and cold air;
• the right knob, mechanically operated via a cable, controls the opening of the flaps which regulate the distribution of air flows;
• the centre knob electrically controls the ventilation of the air at four different speeds.

The operation of the fan at different speeds is achieved through a resistive divider, protected by a special thermal fuse to prevent overheating.

On the controls unit, there is also a button for switching on the 'recirculation' function and the heated rear window See E3030 HEATED REAR WINDSCREEN AND DOOR MIRROR DEFROSTING.

The fan is supplied by a line protected by a specific fuse and is controlled by a specific relay in the engine compartment unit.

The controls unit is supplied by a ignition-operated line protected by a fuse in the unit under the dashboard.
