Housing Assembly
IHKA E32 HOUSING ASSEMBLY
The housing assembly is mounted behind the center of the instrument panel. Most of the climate control system components are mounted either inside or on the housing: 10 stepper motors (for flap control), heater cores (left and right), an evaporator, 4 temperature sensors, the IHKA control module, the blower motor, and the blower final stage unit
In June of 1990, the housing assembly was modified to accommodate a microfilter, which slid into the right side of the housing assembly between the final stage unit and the evaporator core.
