Switch Panel (IHKA): Notes

An integral control panel on the IHKA module contains switches for system control inputs and a display to provide system status information.

The IHKA control system controls the operation of the refrigerant system and the control flaps in the heater assembly to control the temperature and distribution of air in the vehicle interior. It also outputs signals to the BC1 to control the fresh/re-circulation air servomotor and to the blower to control the air volume.
