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; two versions are available: one with three speeds and one with four speeds;
The operation of the fan at different speeds is achieved through a resistive divider, protected by a special thermal fuse to prevent overheating.
There is also a sliding knob on the control panel, located under the knobs, which mechanically regulates the ''recirculation'' function via a cable.
The control panel is lit up when the side lights are on.
The fan circuit is protected by a specific fuse, in the junction unit in the dashboard, controlled by the passenger compartment air fan relay, located in the duct/distributor unit.
The fan only operates when the ignition is switched ON.

The fan circuit is protected by a specific fuse, in the junction unit in the dashboard, controlled by the passenger compartment air fan relay, located in the duct/distributor unit.
The fan only operates when the ignition is switched ON.
The vehicle climate is controlled via a duct/distributor unit with heater and controlled by means of three control knobs in the dashboard:
- the middle knob controls the mixture flap mechanically between hot air and cold air;
- the left knob mechanically controls the opening of the flaps that regulate the distribution of the air flows by means of a flexible cable;
- the right knob adjusts the ventilationof the air, via an electrical control, at four different speeds; two versions are available: one three speed and one four speed.
The control for the different fan speeds is achieved by means of a resistive distributor protected against overheating by a special thermal fuse.
There is also a cursor on the control unit located under the knobs that adjusts the recirculation function mechanically by means of a flexible cable.
The control unit is lit with the side lights on.
See E2010 SIDE LIGHTS / NO. PLATE LIGHTS
The fan circuit is protected by a specific fuse and controlled by the passenter compartment air fan relay in the engine compartment junction unit.
The fan can only be switched on with the ignition ON.
