Air Conditioner Control: Description

The front air control provides regulation of the vehicle's interior temperature. The system is based on the position of the front air controls temperature switch selected by the driver. This is done by utilizing a microcomputer, also referred to as the front air control, which receives input signals from the following three sensors:

• Ambient sensor
• Intake sensor
• PBR (position balanced resistor).

The front air control uses these signals (including the set position of the temperature switch) to control:

• Outlet air volume
• Air temperature
• Air distribution

The front air control also provides separate regulation of the vehicle's interior temperature for the rear passenger area. The system is based on the temperature and rear blower settings selected from rear air control (front) control dials located in the overhead console, or from the rear temperature and blower settings from the rear air control (rear) control dials, when the REAR CTRL switch is pressed (indicator light is on) on the rear air control (front).

The front air control is used to select:

• Outlet air volume
• Air temperature/distribution
