1 - Control for heating and air conditioning system
q   with air conditioning system control unit -J301-
t  connected to other control units via a data bus
t  receives information about the heating and cooling output requirement and sends corresponding signals to the regulating valve for the compressor or the temperature flap control motor
t  is checked in the self-diagnosis → Chapter
2 - Plug - air conditioning wiring loom
3 - Plug - vehicle wiring loom
4 - Flex shaft
q   for positioning unit for air distribution flaps
q   removing and installing → Chapter
