System Description
INFOID:0000000005514689
The upper ventilator door motor is attached to the heater & cooling unit assembly. The upper ventilator door
motor operates by the UPPER VENT switch ON/OFF. Motor rotation is conveyed to a rod which activates the
upper ventilator door.
SYSTEM OPERATION
• The A/C auto amp. receives data from each of the sensors.
• The A/C auto amp. sends air mix door, the mode door, the upper ventilator door and the intake door opening
angle data to the air mix door motor LCU(s), the mode door motor LCU, the upper ventilator door motor LCU
and the intake door motor LCU.
• The air mix door motor(s), the mode door motor, the upper ventilator door motor and the intake door motor
read their respective signals according to the address signal. Opening angle indication signals received from
the A/C auto amp. and each of the motor position sensors are compared by the LCUs in each door motor
with the existing decision and opening angles.
• Next, HOT/COLD, DEF/VENT, OPEN/SHUT or FRE/REC operations is selected. The newly selected data is
returned to the A/C auto amp.

The air mix doors are automatically controlled so that in-vehicle temperature is maintained at a predetermined
value by the temperature setting, ambient temperature, intake temperature and amount of sunload.
SYSTEM OPERATION
• The A/C auto amp. receives data from each of the sensors.
• The A/C auto amp. sends air mix door, the mode door, the upper ventilator door and the intake door opening
angle data to the air mix door motor LCU(s), the mode door motor LCU, the upper ventilator door motor LCU
and the intake door motor LCU.

AIR MIX DOOR CONTROL SYSTEM
When ignition switch is ON, the A/C auto amp. continuously and
automatically controls temperatures regardless of air conditioner
operational condition. When setting a target temperature with the
temperature control switch, the A/C auto amp. corrects the set tem-
perature and decides a target air mix door opening angle. The A/C
auto amp. controls air mix door according to the target air mix door
opening angle and current air mix door opening angle, keeping an
optimum air mix door opening angle. When the temperature is set at
18
°
C (60
°
F), air mix door is set on full cold, and when the tempera-
ture is set at 32
°
C (90
°
F), it is set to full hot.
