DESCRIPTION OF OPERATION
Both front seats are equipped with rheostat-controlled electric heating.
Heating pads 64D and 64P are supplied with current via fuse 10 and switched on and off by temperature sensors, 254D in the driver's seat and
254P in the passenger's seat. The temperature sensors consist of an NTC resistor, the resistance of which varies with the temperature of the heating
pad.
The temperature of the front seat heating pads can be adjusted by means of rheostats 252D and 252 P. These have four positions: 0-1-2-3. Heating
is not activated in position 0, maximum heating is obtained in position 3. When the heating pads reach the preset temperature for each rheostat
position they are switched off and switched back on again when their temperature drops to the lower limit for each rheostat setting.
FAULT DIAGNOSIS HINTS
1. Turn the ignition switch to the Drive position.
2. Check that fuse 10 is intact and that current is supplied to rheostats 252D and 252P.
