Climate Control System - Vehicles With: Dual Automatic Temperature Control (DATC) - System Operation and Component Description: Auto

When AUTO is selected:

• the HVAC system operates to achieve and maintain the temperature requested 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 compressor is automatically controlled by the PCM based on temperature information sent by the HVAC control module. The A/C compressor does not operate if the outside temperature is below approximately 0°C (32.0°F).
• the blower motor speed is automatically controlled through the blower motor speed control when it receives a PWM signal from the HVAC control module based on the temperature setting, but can be manually adjusted if desired.
• 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.
• the dual zone auto can be turned off by holding button for two seconds.
