FUNCTIONAL DESCRIPTION - HEATER - Fiat 500 1.4 16v
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 H081 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.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.
