Rear Air Control
TEMPERATURE CONTROL DIAL (TEMPERATURE AND MODE CONTROL)
The temperature increases or decreases the set temperature. The mode also changes from foot at full hot setting, to foot/vent at mid-range (warm) setting,
and then to vent at full cold setting.
REAR BLOWER CONTROL DIAL
When the rear blower switch (front) is in the OFF position, the rear blower motor cannot operate. When the rear blower switch (front) is in the REAR
position, it allows the rear blower switch (rear) to control the rear blower motor speed. In any other position (1-4), the rear blower switch (front) controls
the rear blower motor speed regardless of the rear blower switch (rear) position.
Front Air Control
COMPONENT DESCRIPTION
Front Air Control
The front air control has a built-in microcomputer which processes information sent from various sensors needed for air conditioner operation. The air
mix door motors, mode door motor, intake door motor, defroster door motor, blower motor and compressor are then controlled.
The front air control is unitized with control mechanisms. When the various switches and temperature dials are operated, data is input to the front air
control.
Self-diagnostic functions are also built into the front air control to provide quick check of malfunctions in the auto air conditioner system.
