The relay
J35
controls the heater
fan circuit.
The supply at the relay contact arrives
from the battery from the line for the maxifuse
J/B1 of B5 protected
by fuse F12 of the junction unit B1, whilst the energizing of the
coil is controlled by the ignition (INT/A) from the line protected
by fuse B27.
The relay
J35
supplies the control
knob
H81
: this controls the fan at the different speeds through
the regulator
O30
.
The voltage control signal varies according
to the position of the knob and either passes or does not pass through
the resistors of the regulator
O30
determining the four
different voltage signals for the fan
N85
which sends external
or recirculation air to the duct/distributor unit at 4 different
speeds.
The control panel symbols are lit up when
the side lights are switched on by lights
G45, supplied through
the line protected by fuse F3 of the junction unit B1. See E2010 SIDE LIGHTS / NO. PLATE LIGHTS
