Electronic Automatic Temperature Control (EATC): Notes

The EATC system heats or cools the vehicle interior depending on the function and temperature selected. The function selection determines heating or cooling and air distribution. The temperature blend control setting determines air temperature.

The EATC components are used to:

• automatically determine the climate control settings based on the temperature selected and ambient conditions (AUTO mode).
• select the air inlet source (outside or recirculated).
• select the blower motor speed.
• select the discharge air temperature (temperature blend).
• select the discharge air location (defrost, panel, floor).
• select the A/C compressor clutch operation.
