Functional description
Fan N85 is supplied when the ignition is switched on (INT/A) from the line protected by fuse F31 of the junction unit B2 under the facia and controlled by relay T8 and dedicated fuse F8 of the engine compartment junction unit B1.
Control knob H81 controls the fan at different speeds via regulator O30: the control signal - earth signal - varies according to knob position and crosses or does not cross the coils of regulator O30 to determine four different voltage signals for fan N85, which thus turns at 4 different speeds.
