2889419 - E6010 HEATER - Description (Heater)

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 air ventilation at four different speeds; two versions are available: a three speed and a four speed one.

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 cursor on the control panel, located under the knobs, which mechanically regulates the "recirculation" function via a cable. For more details,  see DESCRIPTION AND OPERATION: 5020  HEATERThe control panel is lit up when the side lights are on.The fan circuit is protected by a specific fuse, in the junction unit, controlled by the passenger compartment air fan relay, located in the duct/distributor uni.The fan only operates when the ignition is switched ON.
