Climate Control System - System Operation And Component Description: Auto

When AUTO is selected:

• the HVAC system operates in a manner to achieve and maintain the temperature set by the operator.
• the driver and passenger side temperature doors are automatically controlled by the HVAC control module based on the temperature setting.
• the A/C electric compressor is automatically controlled by the SOBDMC from information sent by the HVAC control module, based on the temperature setting. The A/C electric compressor does not operate if the outside temperature is below approximately 33.8°F (1°C).
• the blower motor speed is automatically controlled through the blower motor speed control that receives a PWM signal from the HVAC control module based on the temperature setting, but can be manually overridden.
• the HVAC control module controls the air inlet door to recirculate, partially recirculate or open to the fresh air position depending on the in-car temperature and humidity sensor inputs.
