DESCRIPTION - AIR CONDITIONING - Fiat 500 1.3 Multijet
The manually operated air conditioning system integrates the heater with the function of producing cold and dehumidified air achieved by switching on the compressor and the cooling system.The vehicle climate control system is operated using the four control knobs:
FUNCTIONAL DESCRIPTION - AIR CONDITIONING - Fiat 500 1.3 Multijet
The passenger compartment air fan N085 receives a power supply along the line operated by relay T08 and protected by fuse F08 both located in the engine compartment junction unit B001 (pin 63 of connector B).The coil for relay T08 of B001 (pin 45 of connector B) receives an ignition-controlled power supply (INT/A) along the line protected by fuse F31 of the Body Computer M001 (pin 21 of connector C). This line is excluded during engine starting.The speed of fan N085 is regulated through the H080 fan control which, via the O030 regulating resistance, allows the fan motor to be connected to earth through different resistance values, thereby regulating the speed.If the ring nut is pressed with the selector set to at least the first speed, the climate control system H080 (pin 2 of connector B) sends the compressor engagement request to the electronic thermostat N086.Depending on the temperature measured by the sensor on the evaporator, N086 enables the engagement of the compressor by means of a positive signal sent to pin 49 of connector B of the Body Computer M001.The LED in the ring nut signals that the compressor has been switched on.Switching the side lights on (pin 51 of connector D of M001) turns the two air conditioning/heater control lights on G045 A and B by means of a dedicated positive signal supplied by pin 12 of connector B of the Body Computer.
