The seat heating relay
J62
controls the circuit in question.
The coil of relay
J62
is energized
by the ignition-operated line (INT/A) of the relay
R1
protected
by the fuse
F9
: both are contained in the junction unit
B1
.
The supply to the relay's contact comes
directly from the battery from the specific fuse
B20
. This
supply reaches the switches located on the seats through the connection
D70
B (left seat) and
D71
B (right seat): when the
switch on the seat is pressed, the resistors of the heaters in the
right and left seats, connected in parallel, are supplied until
a thermal contact in the heaters disconnects the resistors when
the temperature exceeds a certain limit. An ignition-operated led
(INT/A) - line protected by fuse
F5 of the junction unit B1 -
illuminates the switch.
